Custom Error 404

I am designing a network of Internet sites on NT5 using PHP. However, when I go live with the network, it will be on a Linux system using PHP. My sites are handled somewhat uniquely. When a visitor (or a component of the network) enters a URL address, the address does not really exist! They are given a custom 404 error page that determines what information/site they are trying to view and the page is then created. I need to know if Linux handles custom error messages the same as NT5. Here's the scenario: Let's say I call the following page: http://domain.com/site/index.html?anyvar=yeah The page does not exist so the custom error page is called. For now, I have phpinfo() in the custom error page. On NT5, the following appears under the phpinfo(): SCRIPT_NAME = name of error page QUERY_STRING = 404;http://domain.com/site/index.html?anyvar=yeah Is this how the query string will appear on a Linux machine? I need to know in order to parse the string right... If it will appear differently, please let me know how. Thanks in advance!! _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com
