Creating login session via CURL

Not sure its a session issue, i think it has to do with the fact that WordPress Dashboard uses relative links.

A quick hackish fix would be to add

curl_setopt($ch,CURL_COOKIEFILE, '');  // Enables session support

Then, add this after closing the curl handler redirect to the actual dashbard location:

curl_close($ch);
header('location: blog/wordpress/wp-admin/');
die();
