Ivan,
Yes I did forget which forum I was posting to (happens when you answer so many questions in both forums).
I was not suggesting that Mohammed needed esri's support for fiddler or Fire Bug, just that he could use esri's tech support to help with his issue if he was not comfortable using a HTTP request web debugger like fiddler and fire bug... Some times experienced developers like us suggest things that seem overwhelming to beginners (Just what I have noticed over the years of supporting the Flex forums).
