RE: [PHP] [php] how to make 404's revert to homepage on a virtual server?

Thanks for the info. Currently my httpd.conf does not contains an errordocumnet line? I could add one but what I can't understand is there must be one because I get the custom raq error page when I try for example. www.scottincz.com/rubbish.html Where is this page stored on the raq and what config file points to it?

You can do this for all virtual sites by putting it in the apache main configuration. Let's assume you have a script that's located in the virtual web server's root, named "404.php". In your httpd.conf, you'd add the line ErrorDocument 404 /404.php On any 404 error, Apache would try to run this script, located in the virtual hosts docroot folder. There's only one thing that must be done on every site - the "404.php" must reside within the virtual server's document root. This can as well be a symbolic link, so you may want to put this line in the script that's configuring a new site: ln -s /<main_host_docroot>/404.php /<virtual_host_docroot>/404.php Failing to make this handler accessible results in a cascaded 404 error by Apache. Ok, what the handler can do: "404.php" is executed as any other PHP script, where the $_SERVER superglobal contains the following additional entries: - REDIRECT_STATUS The HTTP error number (always 404 in this example, but you could use the very same handler for different HTTP errors) - REDIRECT_URL The path that caused the error (e.g. "/blah/nada.php") - REDIRECT_REQUEST_METHOD GET , or POST, or whatever - REDIRECT_QUERY_STRING The URL query string, if any (everything after the question mark), in its original form (parm=value&parm=value) query=something - REDIRECT_ERROR_NOTES Human-readable explanation as given by Apache Your handler script may examine these and proceed as required. The usual $_SERVER entries apply; e.g. the hostname of the virtual server can always be found in $_SERVER['SERVER_NAME']. Hint: you can easily examine all entries by creating a script containing nothing but <?php echo phpinfo(); ?> and register this as Apache error handler. HTH, -- >O Ernest E.
