Readfile, JSP

Hey, soultion for below problem:

<?php

   #$remotefile =
"http://www.newsgenerator.com/newsgenerator/scripts/notexist.jsp";

$remotefile="http://www.trainerslink.com/index.jsp";

   readfile($remotefile);

?>

Where the readfile work for www.trainerslink.com/index.jsp but not the one
that I had comment out.

Beside readfile, any feacture I can use to read the remote server file.

Thanks.
