Superb.

It took a bit more tweaking than I thought, but for anyone who cares, the final plugin code looks like this:

PHP Code:

$UserAgent = $_SERVER['HTTP_USER_AGENT'];
$UserAgent = str_replace(" ", "%20", $UserAgent);
$Rotatordata = file_get_contents('http://www.MySite.biz/Rotator.asp?UA=' . $UserAgent); 


the ASP page can read the user agent like this:

sAgent = Request.QueryString ("UA")

and all is right with the world.

Thanks for your help!
