Not sure how to go about this...basically we need to perform load testing on a web application, but the problem is, all the pages are accessible only by authenticated users. The authentication is performed by the application itself (ie NOT HTTP auth), by means of a form in the login page; once the user authenticates, session info is stored in a cookie which is sent back with each request to prove authentication to the server, and the user can access all the pages.

In the past, I've used tools like Siege for this kind of thing, but it seems it can't do authentication. Is there any tool that can do what we need? Thanks.

You may want to have a look at Selenium. There are also several spinoffs that provide similar functionality. I have never used it myself, but I have had a demo from somebody showing me exactly this kind of thing, i.e. the test tool requests a page, fills in the credentials, logs in and performs the test.

Selenium, Watir/Watin or iMacros all allow you to script test cases in real web browsers.

Thank you all. Looks like either Selenium or iMacros, although the various Wati* are good but they have more prerequisites (eg ruby, .net etc.). – homer5439 May 20 '11 at 12:24
