Yeah, I think zshare is blocking all requests that aren't either zshare.net or localhost.. but
http://www.uploadmirrors.com uploads to them somehow..
If I do:
$src = file_get_contents("http://dl023.zshare.net:3000/uberupload/ubr_link_upload.php");
die($src);
From the server on my computer (localhost) it returns the page right away. However if I try it from any hosting online the page just times out.
