Burp Extension - CPH
Custom Parameter Handler - a Burp extension for powerful manipulation of HTTP messages and macros!

This extension provides a simple way to modify any part of an HTTP message, allowing manipulation with surgical precision even (and especially) when using macros. Typically, macros only support HTTP parameters (name=value), but with this extension anything can be targeted as if it were a parameter.
