allow_url_fopen ini directive not enough

Hi,

I would like to see a new directive to go alongside "allow_url_fopen" to
allow people to turn on or off the ability to include/require a remote file.

The ability to include and execute a file as php from a remote host
leaves many applications open to cross-site-scripting attacks.
This would be easily avoidable if we had a directive
(allow_url_include?) that by default removed this capability.

Any thoughts?
