Note: This topic applies to Web Vuser protocols only. For a list of Web Vuser protocols, see Web Vuser Types.
VuGen creates Web Vuser scripts by monitoring and recording the web traffic that flows between a web browser and a web server while you perform typical business processes. The web traffic includes HTTP requests sent by the browser to the server, and the HTTP responses returned by the server.
When you run a Web Vuser script, the resulting Vuser communicates directly with the web server without relying on a browser or client software. To perform this communication, the Vuser script sends web API functions directly to the web server.
