fsockopen, fwrite problem

hi,

this isnt really an fsockopen or fwrite problem as such! i'm using the following code...

function http_spawn($page)
{
       $basepath=ereg_replace('[^/]*$', '', $_SERVER['PHP_SELF']);
       $cbSock=fsockopen('localhost', $_SERVER['SERVER_PORT'], $errno, $errstr, 5);
       if ($cbSock)
       {
           fwrite($cbSock, "GET {$basepath}{$page} HTTP/1.1\r\n"
               ."Host: {$_SERVER['HTTP_HOST']}\r\n\r\n");

         while (!feof($cbSock))
      {
            echo fgets($cbSock, 128);
      }

       }
   }

http_spawn("page.php");

to kick off a call to a page. got the code from...

(http://ie.php.net/ignore_user_abort)

anyway, this works fine on one server i tried it on. a redhat linux server(apache 2 i think). works perfectly. then i tried the same code on a different server and i'm getting 404 errors...
