The main software component of Flight Load Tester is called the Flight Simulator. This does the actual load testing work by requesting webpages as if it were a user of the site (or as if it where hundreds or thousands of users of the site).
Cookies are supported, allowing the system to work with sites that use sessions.
Support is soon to be added.
This program allows you to record the steps you make as you visit a site. The result of doing this is a file which you can 'replay' with Flight Simulator.
Cookies set by the server are ignored (Flight Simulator takes care of them), but cookies which appear to have been set at the client (e.g. by browser scripting) will be recorded.
Unfortunately, posted form data is not currently captured
Conditional requests by the browser for objects Flight Recorder has seen before will be recorded relatively. i.e. Flight Simulator will be able to make the condition an object's actual last modification time, rather than the value when the script was recorded.
