Description:
------------
For me, following the link to the variadic function doc on the frontpage, when visiting http://php.net, misdirects to the manual lookup page on php.net, instead of redirecting to the right page on a mirror.

Ferenc asked me to report this here.

The issue depends on my IP; I'm using German T-Online with IP 91.53.9.6 at the moment, when it does not work.

See expected/actual results, "expected" from a different IP address somewhere else in Germany, "actual" from my home IP.

(NOTE: I manually added spaces between "http" and "://php.net..." below, because otherwise the bug tracker tells me "SPAM detected". Sigh.

Test script:
---------------
wget http ://php.net/functions.arguments.php

Expected result:
----------------

I had a hard time reproducing the problem, as I was getting properly redirected to a mirror where the docs are working properly, but it seems that the https url can be used to reproduce the issue consistently:
https://www.php.net/functions.arguments.php
 [2014-08-29 11:24 UTC] tyrael@php.net 
https://php.net/functions.arguments seems to be working and from a quick look find_manual_page($LANG, $URI) also expect the $URI to be without any file extension.
this still doesn't explain why was it morking for the mirrors or why do you not get redirected to the mirror in some cases.
I'm gonna update the NEWS entry with the removal of the .php suffix and that should solve the issue though.

It's also producible using "http://..." by adding an "X-Forwarded-For" header.
