Loading an external xml file (simplexml_load_file)

[Scanu]

Why can't i load an external xml file?! This is my code

PHP Code:

$file = 'http://site.com/file.xml';
$xml = simplexml_load_file($file); 


And this what i get

Warning: simplexml_load_file(http://site.com/file.xml) [function.simplexml-load-file]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in [path]/includes/class_bootstrap.php(430) : eval()'d code on line 347

Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "http://site.com/file.xml" in [path]/includes/class_bootstrap.php(430) : eval()'d code on line 347

Does vBulletin allow loading external file?
