Random.php on another sub-domain

koury

I followed the instructions for the random.php hack found on this website, but my server that I have zenphoto is calyou.cup.edu and I'm using the file on sai.cup.edu. I was wondering if there is anyway that you could still @readfile and it would go to the zenphoto server instead of just looking for it on the server with the php file that has the @readfile("");
