POST data getting lost: Content Length = 0

问题


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.
