Tracing xmlhttp traffic
I am writing an web application which uses xmlhttp and HAS (for company reasons) to run in Internet Explorer. To help me debug this application, I need to be able to trace the actual xmlhttp traffic between browser and server. I know that Firefox has tools (eg. GreaseMonkey) to do this, but is there anything available for Explorer? I don't exactly know what proxy servers do, but can they be used for this purpose?
Any help would be appreciated.
