Cross Browser Testing (CBT) consists of: • Single URL • Transactional • Remote Access

Note that many pages and tabs in the Gomez Portal do not display the new product names.

Operational Dashboard The Operational Dashboard now depicts the status of both internal and third party contributors, allowing you to more readily determine an issue's root cause. Additionally, links to the new One Chart interface allow you to easily view relevant trends.

One Chart The Gomez Portal now offers a new multi-product, multi-dimensional charting interface called One Chart. These new charts allow you to quickly view trends and determine the root cause of problems by exposing a larger set of metrics and dimensions. Included products in this version are Backbone, Last Mile, Private Last Mile, Private Backbone, Mobile, First Mile and Benchmarks. You can view predefined charts or create and save custom charts. One Chart also provides drilldowns, via the chart's legend, to existing classic charts to help you obtain more details. Additionally, One Chart features Contributor Group charting, as well as the ability to chart longer time duration greater than 33-days.

Current Limitations • In One Chart, certain metric/dimension combinations are not yet functional, including:

o Number of Connections by Host o Number of Connections by Contributor Group o Number of Hosts by Contributor Group o DNS Time by Host o DNS Time by Contributor Groups



• In One Chart, certain metrics are not aggregating based on the number of tests/pages in chart and legend, including:

o Number of Objects o Number of Bytes

• The newest version of the Gomez First Mile appliance produces an extended metric set which can be

charted within One Chart. Customers who have not been upgraded to the latest version of the appliance will produce charts with no data if a new metric is selected to chart.

Internet Health Map The Gomez Portal now has an Internet Health Map which provides a geographic view of aggregate Backbone and/or Last Mile performance. This near real-time view of user experience lets you quickly identify if your performance issues in a particular geographical area are part of a broader Internet slow-down. The interface allows users to drill into key geographies and select from one of six different metrics.

Test Search The Gomez Portal now features a multi-product test search that lets you easily find Backbone, Last Mile, Private Last Mile, Private Backbone, Mobile, and Benchmark tests. The new search engine matches search criteria against test name, step name, or URL and allows navigation to One Chart, classic charts, or test configuration.

Miscellaneous Portal Changes Other changes to the portal include the following:

• The Node Manager has been updated to indicate which nodes are streaming, UTA, or Browser Agent.

• The Portal banner now displays the username along with the account name.



Cross Browser Testing (CBT) Cross Browser Testing comprises Single URL testing (formerly Reality View XF), Transactional testing (formerly Reality Check XF) and Remote Access. Cross Browser Testing is Gomez’s on-demand cross-browser testing solution. Cross Browser Testing provides designers, application developers and the entire QA and IT team a method to ensure that your Web and mobile applications render and function optimally across the browsers, operating systems, and mobile devices that matter. Cross Browser Testing automates the validation of Web and mobile sites across all major browsers, operating systems and devices. Use Cross Browser Testing to easily identify and resolve Website rendering issues. Use Cross Browser Testing as a QA testing tool that automates problem identification and eliminates blind spots across the entire Web application delivery chain – from device to data center.

New Features and Enhancements The following is a summary of the major features and enhancements in Cross Browser Testing. For more information, refer to the online documentation.

Mobile Readiness Score Integration The Mobile Readiness Score has been updated based on W3C and several other current tests, indicating optimization techniques for websites to be rendered on mobile devices.

Online Help Online Help for Cross Browser Testing is now available. To view the help in the Gomez Portal, select Online Help from the Help menu and then select Browser Tests from the TOC.

Mobile Device Profiles, Supported Operating Systems, and Browsers In this release, Cross Browser Testing has increased the number of mobile device profiles and supported operating systems and browsers.

RenderInspector™ Improvements RenderInspector now has these new features:

• You can now select to view the location of a focal point for each capture image. • RenderInspector no longer uses Flash to select focal points. You can now use Silverlight (for

Internet Explorer and Safari) or HTML 5 (for Firefox and Chrome).

Current Limitations None at this time.



Gomez Recorder The Gomez Recorder and Multi-Browser testing platform represent the next generation in creating scripts.

New Features and Enhancements The following is a summary of the major features and enhancements in the new Gomez Recorder. For more information, refer to the Gomez Recorder online documentation.

Flash Interactions Flash interactions are supported by the Gomez Recorder when recording and playing back a script:

• Recording. The Gomez Recorder now supports recording interactions with a Flash object. Recorded actions include mouse moves, clicks, keyboard typing, and network activity. In addition, the Enable Flash Playback option (shown on the Playback tab) is on by default. When recording, you will notice Click, Move (mouse moves), Type, Wait (time criteria), and Wait (network criteria) actions created for Flash objects.

• Playback: Firefox Agent supports playing back Flash interactions recorded with the Gomez Recorder. This support is currently limited to local playback from the Gomez Recorder and playback from GPN Backbone nodes. Playing back Flash interactions in the IE agent is not currently supported; actions performed on Flash objects when playing back in IE will be ignored.

HTTP Agent The Gomez Recorder now includes the ability to configure a script for playback on Reality Load's HTTP Agent. This new agent runs a script through Firefox once, then using the objects that Firefox generates, will run the same network requests many times, resulting in significant scaling. You can configure content captures, substitutions, and validations that will be applied when running the script in the HTTP agent. The configuration details for Reality Load are stored with the normal script, and can be uploaded to the GPN or saved to disk through the Save functions in the Recorder.

Record-via-Proxy You can now use the Gomez Recorder to record HTTP/S traffic capture from an included proxy server for playback. While this feature is most likely to be used when recording native applications on mobile devices, it can also be used for any application that can be configured to use a standard HTTP/S proxy.

New Wait Type: Wait for Event The recorder and agents now support a new Wait type: Wait for Event. This wait type allows the agent to wait for either the DOMReady or the Onload event of a particular window of the browser.

Wait Action Time Stamping For troubleshooting or visualization purposes, the Gomez Recorder and agents support a time stamping feature. For all types of Wait actions, you can select to display a vertical line. This line will appear in the waterfall view shown in the recorder and indicates the wait's completion time. This feature can be



particularly useful for visualizing DOMReady/Load events. Note that this functionality is not available in the GPN at this time.

Reply Handling on HTTP Actions The Gomez Recorder and the Firefox agent now support reply handling so that content can be retrieved from an HTTP action and used in a future action or validation

Client-side Certificate The Gomez Recorder and Browser agents now support client-side certificates used during both record and playback. This allows sites that require Client SSL Authentication to be recorded and played back in either agent on all products.

DNS Preloading The Gomez Recorder and Browser Agents now support preloading IPs for various host names, skipping DNS lookups for those hosts.

Google Page Speed The Gomez Recorder and Browser Agents now can run Google Page Speed on your web site as the transaction runs. Google Page Speed is a set of industry-wide best practices and rules that are evaluated against your page on the client while the script runs. It provides you with an evaluation of how your site utilizes those practices and a numeric score. Page Speed results are listed in the step results automatically and are available on local playback in the Gomez Recorder.

HTTP Archive (HAR) Export The Browser Agents now produce a standard HTTP Archive (HAR) file with results. This file can be exported for use in other tools.

Improved Results View Results of playing back a script locally include headers, POST content, and reply content, all in a more advanced, accessible results view.

Copy/Paste Action You can copy and paste an action within your script and between scripts by right clicking on an action.

Current Limitations The Gomez Recorder has these limitations:

• The IE Agent is currently limited to two connections per host. This can be overridden on a per-script basis in the Gomez Recorder. Click Script, select the Profile tab, and then under Concurrency Limits, change the value in the Concurrent connections per host (max) field.

• When using multiple windows, only one window should play back a script at a time, or the playback will freeze or fail.

• On Windows 7, IE playback will always have Flash or Silverlight enabled even if they are not enabled for the script. When run on Firefox locally, or on the Gomez platform, the value of “Enable Flash” and “Enable Silverlight” will be respected.

• Long script or step names can cause display issues in the UI, but do not harm the functionality.



• Scripts saved in this version of the Gomez Recorder may not be able to be opened in previous versions of the recorder.

• The HTTP Agent does not support using a proxy when run from the Gomez Recorder. • The Proxy Recording tool does not support using a proxy. • Flash has these limitations:

o Only wmode=windows is supported for interaction playback. SCoE results will not render properly when played on a backbone node; the content will be rendered as a black rectangle. Although the content is not rendered properly, interaction with the items will still be successful.

o Flash playback success is highly dependent on timing and window size. o When playing back a script in the recorder on Firefox, if the website tested uses Flash and

the local system does not have Flash installed, Firefox may crash and not return a result, leading to the recorder displaying “Playback Agent Communication Error.” To work around this issue, install Flash, or alternatively move the npgswf32.dll out of the playback\firefox\plugins directory.

Contact Client Services for more information regarding Flash limitations.



Real User Monitoring – Browser (Browser RUM) Real User Monitoring – Browser (formerly known as Actual) measures performance from your actual end users' browser to see what paths visitors take and the impact of geography, ISP, browser size and type, operating system, device, and cache have on their experiences. Browser RUM also measures the performance of the Flash technology on your website allowing you to understand real customers’ experiences with this technology. This provides you with information regarding all aspects of your users' experiences to help you understand how their experience affects your business results.

New Features and Enhancements The following is a summary of the major features and enhancements in Browser RUM. For more information, refer to the Browser RUM online documentation.

New Performance Analytics Features Browser RUM now features performance conversion analytics, to analyze how performance impacts conversion on your website. In the portal, you create Paths, consisting of pages or custom events in the order in which you expect your website visitors to follow, then view the performance analytics data to determine the number of visits lost from one page/event to the next and the rate of conversion for the website navigation, in addition to page load times and visitor satisfaction for each sequential page or event.

Abandonment Chart Enhancement For Pages, the Abandonment chart now features three charts. The charts compare the number of abandonment pages with the total page views, the abandonment rate with the number of page views, and the abandonment rate compared to the page load time for a selected period of time.

Improved OS and Device Identification This release features more granular operating system and device identification.

Ability to Create up to Five Group IDs You can now create up to five Group IDs for each Page ID or Flash object.

Ability to Create Custom Event Projects You can now create custom event projects to group multiple custom events in a single entity. A project is a user-defined collection of individual custom events that can be grouped together to facilitate reporting and chart by different aggregation rates.

Collected Page View and Event View Charts New drilldown charts allow you to view all of the collected data for the selected time period for Pages, Flash, Contributor Groups, and Custom Events. These charts are available by drilling down from the Page View, Flash View, Host View, or Event Count charts.

Combined Group ID Capability You can now combine multiple Group IDs into a single combined group ID.



Page tag version 7.0 The Page tag size has been enhanced to include the ability to create up to five Group IDs.

Custom Event Alerting You can now create alerts for named events.

Current Limitations None at this time.



Real User Monitoring – First Mile (First Mile) Real User Monitoring – First Mile measures all real-user web transactions and infrastructure health; collects data on real-user web application usage, performance and availability; measures performance for each web server; and quantifies the number of users impacted by performance problems. Using Gomez synthetic test definitions, First Mile correlates real-user and synthetic performance measurements. It tags real-user measurements for automatic correlation and provides an integrated view of real-user measurements and synthetic measurements. First Mile uses a real-user monitoring appliance, managed securely through the Gomez portal, that auto-discovers and learns of your web server infrastructure for monitoring. First Mile measurement data is securely transmitted to the Gomez portal. With the Operational Dashboard and One Chart, First Mile integrates real-user and synthetic measurements. The dashboards and charts help you to quickly view the impact to real users due to a poorly performing web application and to isolate the problems to the datacenter.

New Features and Enhancements The following is a summary of the features and enhancements in First Mile.

Enhanced Website Performance Analysis First Mile has extended its collection of Web performance data in this release. For Web pages, the page load time metric has been broken down into connect time, SSL time, redirect time, server time, and response transfer time, enabling performance analysts to get to the root cause of the problem faster. For Web sites, First Mile reports aggregate performance measurements for all page views across the Web site, providing a broader view of overall site performance. Page abandonment is also being measured for selected Web pages and for the entire Web site.

Flexible Charting First Mile is fully integrated with a revamped One Chart, which provides a multi-product, multi-dimensional charting interface. All of the new performance metrics are included in the updated One Chart interface.

Summary Report The landing page now contains the First Mile Summary Report for analysis of test/page and Web site performance data. The report provides a summary of key test/page and Web site performance indicators for the last hour. You can drill down from the report data to One Chart charts that provide more detail for the selected item.

Integration with Vantage for Real User Monitoring The First Mile appliance is now a data source for on-premise Datacenter RUM installations. It serves as a quick and easy starting point for new Datacenter RUM customers to take advantage of multi-tier analysis in Vantage Analysis Server and analysis of entry points in Vantage for Java and .NET Monitoring.



Improved Self-Service Configuration Test configuration is enhanced to accept wildcards anywhere after the http:// or https://, allowing the configuration to include Web sites that use dynamically generated URLs. You can also configure per page thresholds for page load time and server time, allowing for greater flexibility in quantifying poor performance. First Mile includes a set of predefined user identification rules that are created automatically. Through the new Manage First Mile User Identification Rules screen, you can create custom rules and manage all rules to ensure accurate reporting of user counts.

Current Limitations First Mile has these limitations:

• First Mile only supports integration with Backbone monitoring. It does not support Last Mile, Active Mobile, Active Streaming, or Actual XF.

• First Mile only supports a single real-user monitoring appliance per account.



Synthetic Monitoring – Last Mile and Private Last Mile Last Mile allows you to validate the speed and reliability of your website from your customers' perspectives by measuring and monitoring website performance from actual desktop connections. Using Last Mile, you can assess how web site changes, geographic location, and bandwidth constraints affect the way your customers experience your website. Gomez's Private Last Mile (formerly known as Private Peer) supplements standard performance testing with dedicated agents located at key internal or external locations, such as across intranets, extranets, or VPNs. By installing the Private Last Mile software on servers, end-user desktop machines, or infrastructure components, you can diagnose and pinpoint bottlenecks, evaluate the impact of infrastructure changes (such as load balancers or SSL accelerators), and gain unparalleled insight into the true performance of your Web applications from key end user perspectives.

Minimum System Requirements – Private Last Mile The system on which you want to install Private Last Mile must have the following:

• Windows XP, 2003, Vista, 2008, or Windows 7 • Pentium 4 or better CPU • 512 MB RAM (2GB recommended to enable Internet Explorer version 7 Private Last Mile testing

agent) • 90 MB of free hard disk space (2GB recommended to enable Internet Explorer version 7 Private

Last Mile testing agent)

Minimum System Requirements – Public PEER The system on which you want to install a public PEER must have the following:

• Windows XP, Vista, Windows 7, Windows Server 2003 or Server 2008 • Physical memory for installation: minimum of 256 MB • Available memory: minimum 16 MB to run the PEER and a minimum 50 MB to run the tests • Gozilla Agent:

o Installation (Gozilla browser agent is supported) Minimum total memory: 256 MB Minimum available memory: 50 MB Minimum free disk space: 50 MB (PEER installation partition) Maximum CPU utilization: 80%

o Runtime (PEER can request Firefox job when Gozilla agent is installed) Minimum available memory: 100 MB Maximum CPU utilization: 80%

New Features and Enhancements The following is a summary of the features and enhancements in Last Mile and Private Last Mile.

NS Lookup, Dig, and Ping Added to Instant Test NS Lookup, Dig and Ping diagnostic tests have been added to the Instant Test feature for Last Mile and Private Last Mile.



Ability to Customize Java Memory Usage for Private Last Mile PEERS An option has been added to the Preferences dialog box for Private Last Mile PEERS that allows you to customize Java memory usage. Select the Memory Settings link to customize the initial and maximum heap size. Note that this new feature is not documented in the Private Peer Installation Guide and the Private Peer Administration Guide as these documents were not updated for this release.

Improved PEER Diagnostic Data Collection Last Mile and Private Last Mile has added these features:

• Ability to capture request/response header information for Browser agent tests. • Ability to collect data as to the DNS servers used by the client for a test.

Last Mile Data Export Enhancements Object Level data responses may now optionally include Request and Response header information. If your data request includes a request for object level data, and the test in question is configured to capture Request and Response headers, any object that has collected that information will include it in the response. Transaction measurement level data responses may now include data for DNS servers configured for the machine that ran the test. If your data request includes a request for data from a test that has been configured to capture DNS configuration for the PEERs, that data will be included in the response.

Ability to Chart Benchmark Groups and Tests You can chart benchmark groups and tests if you subscribe to benchmarks and Client Services converts your regular benchmark test batches into benchmark tests.

Current Limitations If you are enabled to run the Private Last Mile agent, you will see UTA, Firefox, and IE agents as options when creating Last Mile tests. When you create a Last Mile test using the IE agent, you will not be prevented from selecting Public Peer populations. However, selecting a Public Peer population with the IE agent will not produce test results because the IE agent is not available in the public Last Mile.

Known Issues The following are a list of known issues.

Java Socket Timeout Errors You may receive a Java socket timeout error when retrieving request response headers for objects. To avoid receiving this error, increase the default timeout settings.

The Edit Test Page Incorrectly Displays the Request/Response Header Capture Option The Edit Last Mile (Single URL or Transaction): TestName page displays the Request/Response Header Capture option for tests where detailed component or object level data is not stored (the no page objects option was originally selected for this test.) Note that if you select this option for a test where detailed component or object level data is not available, it will be ignored.



Synthetic Monitoring – Mobile (Mobile) Synthetic Monitoring – Mobile provides you a method to identify, diagnose, prioritize, and resolve performance issues, whether they are specific to the mobile Web, specific to the Web, or common to both. Mobile has an active monitoring service that tests and measures the performance of mobile web sites, applications, and Short Message Service (SMS) services by emulating the characteristics of thousands of different devices running on major US and international wireless carriers. The service runs scheduled tests around the clock, delivering alerts when issues arise, with granular reports that pinpoint root causes.

Mobile Web Content Active Mobile allows you to record and to execute scenarios against these types of mobile content: WAP 1.X/WML, WAP 2.0/XHTML, and HTML.

Device Database A device database, which allows you to select mobile phones is accessible from the Gomez Recorder. You can also customize and create your own device.

SMS Scenarios Mobile supports testing basic single-part SMS applications. You can implement Send SMS and Receive SMS steps to monitor the performance and the availability of your SMS service.

Mobile Screen Capture You can record screen captures for a Mobile test. You can select to only obtain screen captures when a test succeeds, fails, or for all instances (success and failure).

Carrier’s Proxy If a proxy available through the carrier’s Access Point Name (APN) is used by the Gomez platform, then you can set up the mobile test to be executed through the carrier’s proxy. This feature is only available when the test is executed on the peer-side, not on the Mobile GSR-side.

New Features and Enhancements The following is a summary of the major features and enhancements in Mobile.

Gomez Recorder Now Supports Proxy Recording You can now use the Gomez Recorder to record HTTP/S traffic capture from an included proxy server for playback. While this feature can be used for any application that can be configured to use a standard HTTP/S proxy, you can also use it when recording native applications on mobile devices. Go to page 7 for more information regarding the new features of the Gomez Recorder.

Mobile Readiness Score A new mobile readiness is presented, based on W3C and several other current tests, indicating optimization techniques for websites to be rendered on mobile devices.



Limitations and Known Issues

SMS The following are not supported:

• Asynchronous SMS • Multi-part SMS • International characters for SMS

Mobile will not treat messages correctly where the sender is a string and not a number.

WAP1.X • Only uncompiled (text format) WAP 1.X content can be used by Mobile, therefore WAP 1.X

gateways and WAP 1.X binary content are not supported. • WML events OnEnterForward and OnEnterBackward are not fully supported.

APN/Speed • You cannot select the APN and speed (2G/3G) used by tests. You can only use the APN and speed

configured on the Gomez platform; usually the configuration chosen is Web APN and a speed of 3.5G.

• For T-Mobile USA, China Mobile, China Unicom, and China Telecom, a speed of 2.5G only is supported.

Mobile GSR If you use the Mobile GSR, note the following:

• Internet Explorer is the browser used to record the scripts in the Mobile GSR; therefore, when recording WebKit-optimized mobile sites, some problems may occur, as the JavaScript code used is not always compatible with Internet Explorer.

• When a mobile test is uploaded from the Mobile GSR, it is not displayed as a mobile test when listed by the Mobile GSR, however the test is fully recognized by the Gomez platform.

• The mobile device database does not yet store the performance parameters of any device: the default values of UTA are used during the download, the simultaneous HTTP request value is 6, and the max concurrent connection value is set to 2. However, you can update these values manually.

Gomez Platform • The Mobile section in the Report page does not provide useful information for Mobile tests;

instead, use the Mobile Saved Chart page to generate daily reports. • All Mobile alerts are included in the same category as Private Last Mile alerts.

New Features and Enhancements The following is a summary of the features and enhancements in Streaming. For more information, refer to the Streaming online documentation.

Supported Features Streaming now supports the following:

• Microsoft Silverlight web browser plugin • H.264 • Authenticated Streaming (Note that Authenticated Streaming requires an authentication token with

an expiration time of greater than 3 minutes.) • Adaptive Streaming

Stream-level Bandwidth Rate Profile You can now limit the bandwidth rate used for a Streaming test. When scheduling a test, you can specify up to five bandwidth rates and the start and end times for each bandwidth rate.

Minor UI Enhancement This release of Streaming includes an enhancement to the UI so that pages which list tests (such as the Status Report page) now display an icon next to the test name to show the type of test (single URL, transaction, or Stream URL).

Current Limitations Streaming has the following known limitations.



Active Streaming Does Not Support: • Digital Rights Managed (DRM) content • URLs in which filenames contain a ‘/’

Server Type Performance Metric The Server Type performance metric does not apply to WMP or Flash.

Some Values are Represented as “0” Due to Rounding • “Initial Connection Time = 0” means Initial Connection Time < 1 ms • “File Size = 0 M” means “File Size < 500 Bytes”



Web Load Testing (Load) Web Load Testing is the only load test tool that can test performance across the entire web application delivery chain.

• Web Load Testing is an on-demand load testing solution that enables organizations to find and resolve more (critical, significant, revenue impacting, business impacting) web application performance, availability and experience problems than ever before.

• Unlike other solutions that do not realistically simulate load from the end-user’s perspective, Web Load Testing generates both high volume and geographic load that proactively identifies problems across the entire “web application delivery chain” – from browser to datacenter.

New Features and Enhancements The following is a summary of the features and enhancements in Web Load Testing. For more information, refer to the Web Load Testing online documentation.

HTTP Agent Support Web Load Testing now supports an HTTP agent. Any Browser Agent script can be run as an HTTP script. However, they can also be tested and configured manually in the Gomez Recorder. HTTP scripts need manual configuration if dynamic substitutions are necessary for navigation. Scripts manually configured can be tested in the Gomez Recorder and then uploaded to the GPN for use in Web Load Testing.

Test Scheduling You can now schedule a test to run as soon as possible. If you select this option, the load test will run as soon as the hardware is available. For tests that are scheduled for under 1000 users, the start time will typically be under 10 minutes, but is contingent upon the datacenter(s) used in the test. Note that the “Start as Soon as Possible” feature precludes using Gomez Last Mile in that Load test. Last Mile still requires 35 minutes to stage and therefore, must be scheduled out to at least that amount of time.

Page Level Chart Error count by host has been added to the Page Level chart.

Mobile Gomez Recorder Support Load can now play back Mobile Firefox scripts that were created using the Gomez Recorder.

Cloud Expansion Web Load Testing has added a new vendor, Terremark/Miami, and a new location, Amazon/Tokyo.

URL Exclusions In this release of Web Load Testing, the limit on the length of the string for URL exclusions has been increased to 1024 bytes.

Firefox Agent Location Expansion The Firefox Agent and Mobile Firefox Agent are now available at all cloud datacenters.



Minor UI Enhancement This release of Web Load Testing includes an enhancement to the UI so that the resources shown in the Master Schedule page and in the Scheduling page depend on your account.

Current Limitations Web Load Testing has the following known issues.

SCOE Limitations SCOE is now supported from all Base Load data centers excluding GoGrid East and Terremark Miami.

Staging Time for Large Load Tests Gomez recommends a staging time of at least 30 minutes for a large load test (more than 5000 users).

IE Agent and Base Load Geographies The IE agent is only available from the EC2 Virginia data center. Selecting this agent type will remove the options to select other datacenters or Last Mile.

Last Mile Configuration Settings While you can select test configuration options for Web Load Testing, these settings will not apply to Last Mile Geographic Perspective tests. To use configuration settings for Last Mile Geographic Perspective testing, modify the settings in the script. Note that you cannot select Last Mile if you select the IE agent or the Mobile UTA agent.

Downloading Files using Internet Explorer If you are using Internet Explorer to view Web Load Testing in the GPN, the first time you select to download a file, a security message appears (“To help protect your security, Internet Explorer blocked this site from downloading files to your computer. Click here for options. “) When you allow Internet Explorer to download the file, the landing page for Web Load Testing appears and you must navigate to the file you wish to download. You can work around this issue by either:

• Adding *.gomeznetworks.com to the list of trusted sites for Internet Explorer. • Using Firefox.

Selecting Percentage of Users for Last Mile Testing Although when running multiple scripts you can select the percentage of virtual users that will run each script, all Last Mile Geographic Perspective virtual users will run through each script in equal percentages.

File Upload File upload is not supported in this release of Web Load Testing.

Unsupported Databank Characters These special characters: the backslash (\), ampersand (&), percent sign (%), and a space ( ) are not supported databank values.




HTTP Agent The HTTP Agent has these limitations:

• Unlike the Browser Agent, the HTTP Agent flags an empty step as a failure step. • NTML authentication is not supported in the HTTP Agent. • SCOE is not supported for the HTTP Agent.
