php 301 redirects actually doing a 302 redirect

Question

I have been googling for this but no one appears to have the answer.

This post describes the problem well:

Answer 1

It appears that the only answer to this one at the moment is to not use FastCGI on IIS7 when using PHP (because of a bug in FastCGI) - which is rubbish because it's very quick. Using isapi allows the 301 redirects to work as they should, but it's not as fast.
