RewriteCond %{THE_REQUEST} ^GET\ .*/index\.(php|html)\ HTTP

RewriteRule ^(.*)index\.(php|html)$ /$1 [R=301,L]

function that does 301 redirects to the proper version of a URL if the visitor isn’t already there.

<?php

// include config file

require_once ‘config.inc.php’;

// redirects to proper category URL if not already there

function fix_url($proper_url)

{

// 301 redirect to the proper URL if necessary

if (SITE_DOMAIN . $_SERVER[‘REQUEST_URI’] != $proper_url)
