HTTP 405 - Resource not allowed Internet Information Services

[LaTicca Peeples]

I have a form in one of my web pages with the following line:

<FORM METHOD="POST" ACTION=$_SERVER['$PHP_SELF']>

even if I write <FORM METHOD="POST" ACTION=test> where test is the form name, I get the same error.

It's the same with <FORM METHOD="POST" ACTION=['$PHP_SELF']>

I checked the ini file for the register globals setting and saw that it was set to off.

Please help me out!
