Web - HTTP/HTML protocol overview

Note: This topic applies to Web - HTTP/HTML Vuser scripts only.

The Web - HTTP/HTML Vuser protocol emulates communication between a browser and web server on an HTTP or HTML level.

When should you use the Web - HTTP/HTML Vuser protocol?

You can use the Web - HTTP/HTML Vuser protocol for browser applications that include applets and VB script, and for non-browser applications.

Use the Web - HTTP/HTML Vuser protocol when the client and the server communication is done over HTTP/S communication, and the complexity of the communication does not require content modification. You can also use it for mobile devices or mobile device emulators communicating with servers over HTTP—for details, see Web - HTTP/HTML for mobile.

If content modification is required, consider using the TruClient protocol. For further information about TruClient, see TruClient protocols.

You can create a script using TruClient - Web protocol and then convert it to Web - HTTP/HTML protocol later, for load testing purposes. For details, see Convert a TruClient - Web script to Web - HTTP/HTML format.

Web - HTTP/HTML Vuser technology

You use VuGen to develop Web - HTTP/HTML Vuser scripts. To record a Web - HTTP/HTML Vuser script, you navigate through a website - performing typical user activities. VuGen records your actions and generates a Web - HTTP/HTML Vuser script. The script contains detailed information about the recorded traffic.

When you run the script, the resulting Vuser emulates a user accessing the Internet. Replay is supported on both 32-bit and 64-bit architecture. You can enable 64-bit replay in the Runtime Settings > General > Miscellaneous tab.

Version support: 64-bit replay is supported from version 24.3.
