User-Agent tags do not a secure connection make. Perhaps doing a wget and directing it to /dev/null (if you're on *nix) would be appropriate to invoke a remote script and pass it parameters. Hell, even wget to standard output if you want, and use that as your "result code." It's basically doing what cURL does, but outside of the PHP script itself. Anyway, I digress. My point is that exec("php http://mysite.com/script.php";) will fail, since it will be reading the remote script's OUTPUT, and not the remote script's SOURCE CODE. HTH, Todd Boyd Web Programmer
