Remote cookie includes

Does anyone know how to call a remote include AND have the include execute remotely. My problem is that with three different methods of includes they all return the php code and execute it locally. I have two domains and I want to write a cookie on 1 then "check it" from 2. The method is to include a script from the first domain and return a variable if it's set. They all load but fail to find the cookie because they are executing it from 2. <? $file = "http://www.mydomain.com/script.php"; // Attempt 1 include $file; // Attempt 2 print join('',file($file)); // Attempt 3 $fp = fopen($file,'r'); print fread( $fp, 99999999 ); fclose($fp); ?> Does anyone know if this is possible? Thanks SOO much! Dean
