HowTo

Server variables are accessible through %{VAR_NAME}. Some of the most useful ones are below:

HTTP_USER_AGENT	This is the client being used to access your server. You can use this to identify the browser being used and show different content accordingly. It also allows you to block certain unfriendly bots from your server.
HTTP_REFERER	The referring page as sent by the browser. Note that this data is unreliable and can easily be modified by the user. You can use this variable to prevent hotlinking.
HTTP_HOST	The current hostname. Possible values include domain.com, www.domain.com, sub.domain.com, an IP address or even your localhost.
SERVER_PORT	The current port. This value is 80 for http, 443 for https (ssl). Useful for redirecting users to force them onto the secure connection.
REMOTE_ADDR	The remote address of the user, also known as the IP. This allows you to block harmful bots or users.
SCRIPT_FILENAME	The name of the requested file. This is the value that would be matched against the pattern of the RewriteRule.
QUERY_STRING	This string contains all the GET data for the request. In other words, everything after the ? in the URL. For example, the QUERY_STRING variable for a request for file.php?foo=bar&pie=good will be \'foo=bar&pie=good\'
REQUEST_URI	The requested URI, a combination of the SCRIPT_FILENAME followed by the QUERY_STRING if there is one.
