Case sensitive URLs - how to make them insensitive?

I'm struggling with mod_rewrite and .htaccess... All I need to do is make my URLs case in-sensitive. After couple of 500 internal server errors and a lot of googling a lot of stack overflowing I'm just looking for one working solution.

NOT working: Convert to lowercase in a mod_rewrite rule

RewriteMap tolower int:tolower
RewriteRule  ^([^/]+)/?$  somedir/${tolower:$1}

NOT working: Case Insensitive URLs with mod_rewrite

All I need is simple not-case sensitive URLs :)

.htaccess mod-rewrite apache

A variation on one of the above from user2305090 which works for me:

First, add the following to your .htaccess file where /forwarding-site-nocase.php is my custom 404 page URL.

ErrorDocument 404 /forwarding-site-nocase.php

Then, at the very top of your custom 404 page, starting on line 1, add the following. If you have a blank line first, it fails.

<?php
$mydir=getdir("/",$_SERVER['REQUEST_URI']);
if($mydir!=false)
{
    $thedomain = 'https://' . $_SERVER['SERVER_NAME'];
    header("HTTP/1.1 301 Moved Permanently");
    header( 'Location: ' . $thedomain.$mydir );
}
function getdir($loc,$tfile)
{
    $startloc=$_SERVER['DOCUMENT_ROOT'];
    if (file_exists($startloc.$loc) && $handle = opendir($startloc.$loc)) 
    {
        while (false !== ($file = readdir($handle)))
        {
            if ($file != "." && $file != ".." && strncasecmp($loc.$file,$tfile,strlen($loc.$file))==0)
            {
            if(strncasecmp($loc.$file,$tfile,strlen($tfile))==0)
            {
                return $loc.$file;
                }
                else
                {
                    return getdir($loc.$file."/",$tfile);
                }
            }
        }
    closedir($handle);
    }
    return false;
}
?>

Now you can follow this with your standard HTML for your custom 404 page such as:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Language" content="en" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="description" content="Company information page - Page Not Found Error"/> 
<meta name="search" content="Company information page - About Us.  Manufacturer of rack mount rugged computer systems and rugged LCD displays for the military and industrial markets" />

and so forth for the rest of the page.

Note I changed the "http://" to "https://" and the error file explicitly to .php, since the original suggested version threw an error.
