php5.2x and Url Includes

I just found out thanks to Steven at WHT that there is a setting in php where you can disable or enable url includes. This feature is disabled by default and there is no directive in php.ini for it. To make it work or add the setting just insert this, I put mine under allow_url_fopen.

allow_url_include = On

This is actually a nice security feature so Id advise to keep it off.
