Description:
------------
When i open with: get_headers() 
http://www.zebis.ch/Unterricht/Fach/Unterrichtsmaterialien/dateizeigen.php?id=4070&vz=ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv&file=symmetrien.doc

I got 302 Found
Location => ../../schublade/ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv/docs/symmetrien.doc

PHP try open:
GET /Unterricht/Fach/Unterrichtsmaterialien//../../schublade/ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv/docs/symmetrien.doc

But it should be:
GET /Unterricht/schublade/ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv/docs/symmetrien.doc

Browsers can handle that (ie, ff, chrome)

this means:
get_headers()  dont execute ../ like browser will do.



Test script:
---------------
<?PHP 
$url = 'http://www.zebis.ch/Unterricht/Fach/Unterrichtsmaterialien/dateizeigen.php?id=4070&vz=ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv&file=symmetrien.doc';
$headers = get_headers($url, 1);
print_r($headers);


Expected result:
----------------
GET /Unterricht/schublade/ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv/docs/symmetrien.doc


Actual result:
--------------
GET /Unterricht/Fach/Unterrichtsmaterialien//../../schublade/ME4gDDrhrBwBKVWwrrubqqAFR9r4Hv/docs/symmetrien.doc
