Very easy but VERY cool to use: For an index.php that will be installed on many servers that are installed in a web without DNS, the page should point to the server itself and, for example for a cups-webinterface to port 631. So, let´s do it: <a href="/testdir/">testlink</a> <a href="http://<? echo apache_getenv("SERVER_ADDR"); ?>:631/">Cups Webinterface</a> Have a lot of fun . . . Hela
