I want to change an HTTP request before sending the data.
I tried WebScarab for the purpose, but it looks like it doesn't work with Facebook properly. (And I dealing with Facebook (https if possible, otherwise http) here)
Is there any good way to change the HTTP request before sending it?
Note: Normally this would be an application that sends data to a locally running proxy server on some other port before sending the data to the server.
Extra: My aim is to edit the name to which the Facebook comments are tagged to. But that's not really important unless you know a way to do the same in a different way.
