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.php
It works well, but I want to know what was the wrong URL that caused this redirection. In other words, I need to fetch HTTP referer while user is in 404.php. So I have used $_SERVER['HTTP_REFERER']
in 404.php, but it does not return anything.
Where did I have mistakes? And what is your solutions to solve this problem?
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
.
