Suru - Web Proxy and Pentest Tool

Suru is a Man In The Middle (MITM) proxy that sits between the user's browser and the web application. It receives all the request made by a the browser and records it. The requests can be modified in any way and replayed. Suru not only catches requests that were made by the user, but also requests that use the IE object, such as rich applications using web services, MSN ads, Google Earth requests, application auto-updates etc. The proxy understands multi part POSTs (MPPs) and XML POSTs (used for web services).

Suru gives the analyst the ability to fuzz ANY part of the HTTP request. This obviously includes GET and POST parameters, but can also be extended to Host: fields, Content-length: etc. The analyst can choose to fuzz any point of the HTTP request header or body.
