Debugging ajax, resend request

This is something that I've been looking for for a while. When I'm debugging my ajax applications I have to keep reloading the whole page, even if the only changes I made were on the server.

For example, in my current a开发者_运维知识库pplication, there is Tinymce being loaded, jQuery UI, I have to click one dialog, to click another to click another. What I would love is the ability in something like Firebug to right click the request and select 'resend' especially when the only change I made is on the server e.g. print_r( $_POST );

The closest I've gotten to this ability is in Firebug on the Net tab, right click the request and click 'open in new tab', which is nearly there - but not quite

You need to replay the HTTP request, thats something firebug isn't meant to do. You need fiddler to get the work done. Fidder2 even has a Firefox addon. You can replay your request using fiddler.
