SYMPTOMS
After an HTTP POST does not succeed, your next try to send a POST may be blocked. The third time you try, and later tries, the POST succeeds.



CAUSE
The POST that does not succeed is blocked when it waits for more information, which occurs because of the POST. Because the first POST does not succeed, no more information is sent. This causes a connection to be leaked, which might create a situation where all available connections are used and you cannot make more POSTs.

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft.NET Framework service pack that contains this hotfix.
