How to find referrer URL while using htaccess 404 redirect?

Question

I\'ve used the code below to create a custom 404 message (page not found) using a .htaccess file.

RewriteEngine On
ErrorDocument 404 https://%{HTTP_HOST}/404.p         


        

Answer 1

Remove http:// from 404 handler and have it like this:

ErrorDocument 404 /404.php

The URL that is causing 404 is available to you in 404.php using:

$_SERVER["REQUEST_URI"]

When http:// ise used in 404 handler server performs full redirection and you loose original REQUEST_URI.
