When you attack a web app, you sometimes have to perform a certain sequence of actions multiple times (e.g. brute-force a password or the second authentication factor, repeatedly use the same resource, etc.). There are plenty of tools designed for this purpose. Which one to choose if you need, for instance, to make five requests over HTTP a thousand times in a row, while maintaining the same session? My choice is Burp Suite, and in this article, I will explain why.
