Fiddler HTTP Debugger

Fiddler HTTP Debugger - A web debugging tool which commonly used by my colleague.

Today, I found a flash file (SWF extension) not loading a xml file correctly during my web development. So, I was thinking is it my false that putting the flash file in a wrong directory or there is some error on the flash file itself?

Suddenly, my colleague help me find out that it is the flash file problem, the xml file must put at a special path in order to make the flash work. It was Fiddler which help us trace which process calling which file at which path having problem.

Actually I had been teach by my colleague to use Fiddler before, but I just alway forgot to use it.

Anyway, here a Firefox Add-ons - Live HTTP Headers, something similar to Fiddler & it works well on Firefox browser.

Do remember to use it when you need it.
