I'm like the others... I have no idea what parasite hosting is.
What's the basic thing you're trying to do - track someone who lands on a page without using javascript and aren't hosting the page yourself so have no means of using your own server side code?
If so, can't you have:
Code:
<img src="htttp://myownserver.com/tracker.jpg"/>
and use mod_rewrite to convert the request for tracker.jpg to a php script which basically does (pretty much pseudo code below -- do not use)
Code:
<?php
ob_start(); var_dump($_SERVER); $to_dump = ob_get_contents(); ob_end_clean();
if($fp = fopen("track.txt","wb"))
{
fwrite($to_dump,$fp);
fclose($fp);
}
echo file_get_contents("path/to/some/image.jpg");
?>
