As a category, once you have a Load Test session, these are the areas that will need addressing
HTTP Response Verification & Failure Actions: Validate HTTP responses and what to do when they are not as expected.
Var Handler: This powerful tool displays detailed information about a recorded URL and supports composing dynamically exchanged session parameters over the entire Web-surfing session. At the Var Handler’s core is extracting values from received HTML pages into variables - from HTML forms or hyperlink-parameters - and to assign such variables to parameters of succeeding HTTP requests, instead of using the "burned in" values of a recorded Web surfing session.
Var Finder: Searches and finds dynamically-exchanged CGI (or form) parameters. Var Finder also supports extracting variables from Input files and from "user input fields" (global load test program parameters).
