$_POST variables coming through empty in IE7 for one subfolder

Question

I\'ve having trouble with $_POST variables not being received from forms within a PHP website.

To clarify the problem, I created this simple PHP script \"POST_test.p

Answer 1

Thanks for the suggestions.

It turned out that the problem was caused by a previous request to an unrelated page which made use of NTLM authentication like this (or similar):

After that authentication was done, all $_POST data was received empty until IE was closed and re-opened. So far, I've worked around the issue by removing the above code and instead arranging for Apache to use NTLM within our Intranet (which sets the $_SERVER['REMOTE_USER'] variable). (Outside of our intranet, Apache authentication is still used).
