http proxy for debugging purposes

Question

I am looking for a preferably free http proxy to be used for debugging purposes.

I already have firebug and firebug lite in my tool set, but firebug lite won't let me see ajax requests in internet explorer.

I thought an intercepting proxy might do the feat

I recommend Fiddler. It lets you track all of the HTTP traffic coming in and out of your application, break in the middle in order to change parts of it, log everything, etc.
