In this section, you will learn how to create advanced Test Plans to test a Web site.

For an example of a basic Test Plan, see Building a Web Test Plan .

If your web application uses URL rewriting rather than cookies to save session information, then you'll need to do a bit of extra work to test your site.

To respond correctly to URL rewriting, JMeter needs to parse the HTML received from the server and retrieve the unique session ID. Use the appropriate URL Rewriting Modifier to accomplish this. Simply enter the name of your session ID parameter into the modifier, and it will find it and add it to each request. If the request already has a value, it will be replaced.

URL Rewriting Example

Download this example . In Figure 1 is shown a test plan using URL rewriting. Note that the URL Re-writing modifier is attached to the ThreadGroup, thus assuring that it will affect every request in that ThreadGroup.

In Figure 2, we see the URL Re-writing modifier GUI, which just has a field for the user to specify the name of the session ID parameter. There is also a checkbox for indicating that the session ID should be part of the path (separated by a ";"), rather than a request parameter

The HTTP Header Manager lets you customize what information JMeter sends in the HTTP request header. This header includes properties like "User-Agent", "Pragma", "Referer", etc.

The HTTP Header Manager , like the HTTP Cookie Manager , should probably be added at the Thread Group level, unless for some reason you wish to specify different headers for the different HTTP Request objects in your test.
