I think what you need to do is return HTTP status of 204 (No Content).
When the browser receives 204 response it will leave the
screen intact, i.e., to the user nothing seems to have happened
while in fact a request gets executed on the server.
The code looks like this:
<?
header("HTTP/1.0 204 No Content"); // when using ISAPI
//header("Status: 204 No Content"); // when using CGI
?>
