We have deployed few reports(.pdf) on our internal website. User initiates the request for these pdf they are intermittently working on Firefox. On Debugging with Tamper Data, Firefox is initiating another request before the 1st is completed. Since the second request is initiated by Firefox without appropriate headers and it fails. I'm attaching all the request headers.

IE has no problem opening the PDF and If I change the Firefox association to Adobe installed on the box, it works fine i.e. when I changed in Option-> Applications-> ContentType & Action ( Use adobe reader 9.1 default) it works fine. Its not working with 'Use Adobe Acrobat in Firefox'. 

I'll be more than happy to provide the tcpip logs.

Where does the X-REMOTE-EMGSESSIONID: header get added? Is that added by a proxy? Is this being downloaded by some Ajax-y site using XMLHttpRequest?

I have no idea why the second request is a byte-range request, maybe we do that in certain error cases? (I'd have to ask our networking guys.) But your server announced "Accept-Ranges: bytes" in the first response so it shouldn't have failed with a 501-NotImplemented. Is your server falsely advertising byte range support? Or am I misinterpreting the 501? maybe it's being used like a 401 except since it's a custom authentication header you can reply with the standard unauthorized status.

Is the problem the lack of the X-REMOTE-EMGSESSIONID: header in the second request? You weren't very specific about what you thought the appropriate headers were, and for normal http traffic what I see looks perfectly fine.
