I've been trying to find a solution for ages with no success. On our app, customers submit a form and on the next page we process it. Sometimes though the data never arrives. This seems to happen for just a few of our customers. Seems to happen with IE7 and using a proxy.

Here's some headers, note the HTTP_VIA:

We've been having the same problem.

POST requests from IE7/IE8 that go through ISA proxy are sometimes (maybe one time in 50) missing the POST data, and have a content-length of 0.

This is a known issue with ISA - see http://support.microsoft.com/kb/942638 which provides a fix.

That link doesn't help us since we don't use NTLM authentication. Thanks though

Do you mean your webserver doesn't use NTLM authentication? That doesn't mean NTLM authentication isn't being done between the user's browser and an ISA proxy.

Ahh, thanks, didnt think of that
