I'm running my test server on Windows XP SP3 and have been successfully running PHP 5 for some time using: php-cgi.exe -b 127.0.0.1:10000 My live server is running on PHP 4 and that gives an incompatibility risk in problem solving. So I've removed PHP 5 on my test server and have installed PHP 4.4.9 but I can't find how I set host and port in php. Running php -v has confirmed that this is the cgi-fcgi version. I'm sure it's simple but I'm being driven nuts. TIA, John
