// TO INSTALL:
//  -Upload this file and two text files to the same directory.
//     hosts.txt - hostnames you want to ban.
//     ips.txt - ips you want to ban.
//  - Use this file as an include on necessary pages.

			header("Location: $url");
		}

		// There was an asterisk.
		// $pos contains the first (and only) occurance
		// of an asterisk, so we can compare the rightmost
		// positions of the strings.

		// Length of string: strlen($buffer);
		// First position of asterisk: $pos
		// Number of characters to the right of the *:
		//	(strlen($buffer)-($pos+1));
