Server NGINX

Hi all

First kudos to all of the maintainers of modules and the nginx team.
Great product guys!!

I am getting an intermittent error where the headers of a 302 redirect
are being shown as the body in the browser. The connect sits for a long
time and then this is show in the browser

Also the 302 is being reported in the browser as a 200.

I have compiled nginx with debug and I am getting:

kolbyjack on irc helped me figure this out. The preceding call did not
return any data correctly, and thus a 0\ was stuck in the buffer. Fixed
the call before the post and voila!
