Have you traced the requests with Fiddler to see exactly what the browser is sending? If the browser sends duplicazte requests there's really not much you can do to fix that on the server end of things.
I would take a close look at the request traces and see what exactly is happening. I do remember this IE problem from way back when on IE 6 (or 5) but haven't heard about that since.
FWIW, the result isn't a PDF is it? PDF viewers will often times fire multiple requests against the backend server (Acrobat definitely used to do that and I've also seen it with FoxIt).

I've run into a really wierd problem running a 4.68 app on a Hyper V (virtualization platform) with a Xeon Quad Core processor running Windows Server 2008 and IIS 7.5.
The application is based on the West Wind Web Store.
The problem is that in certain instances I'm getting the exact same request information twice at the exact same time. Basically it's a request to send an order (this is a business to business app). The first request is serviced and the second one is rejected because it is a duplicate.
The system has been running for 8+ years without a hitch, or at least not one that I've ever noticed. Recently my client upgraded to from a 2003 server to the above configuration. The program appeared to be running correctly for the last month. We just recently noticed the duplicate order problem which appears to occur when the order is submitted from customers with an IE 8 browser running on an XP system.
I've checked and double checked the code and I can't see any problem internally. I know that IE 8 had a problem when a submit was done from Javascript rather then a straight submit button so I eliminated that section of the code.
By the way, when I move the program from Automation to File mode it works correctly making me wonder if there is something wrong with the way I set it up under IIS or if there could be a problem in the way the server is set up or if somehow the "virtualization" is the problem.
I'm open to all suggestions as to where to look next.
Thanks,
