Description:
------------
---
From manual page: http://www.php.net/function.filter-var
---

FILTER_VALIDATE_URL validates wrong when you set two or more urls together, for 
example:

$url = 'http://php.net/http://bugs.php.net/';

I'm using PHP version 5.3.5

Test script:
---------------
<?php
$url = 'http://php.net/http://bugs.php.net/';
var_dump(filter_var($url, FILTER_VALIDATE_URL));
?>

Expected result:
----------------
bool(false)

Actual result:
--------------
string(35) "http://php.net/http://bugs.php.net/"

That's a valid URL: in this case, the path component is http://bugs.php.net/, and 
that's explicitly allowed by RFC 3986 -- path components can include colons.

Oh. I was thinking that was <scheme>://<authority>/<scheme>://<authority> and not 
the path. Now it's clear, thank you.
