Question

I setup a 404 page and it works as it should. I am extracting the “error page” from the URL and using that to create a session since I need to pass it as a variable. My 404 has links to different pages and I would like to keep the referring url all the time even if the following pages exist. For example:

1. http://www.mysite.com/100
2. 100 does not exist and goes to my 404. The url is shown as step 1.
3. Inside my 404 I have links to other pages likes http://www.mysite.com/link.php but I want that to be http://www.mysite.com/100/link.php

How can I accomplish this?

This is how I am passing the variable I need:

$page2 = $_SERVER['REDIRECT_URL'];
$str2 = substr($page2, 1);
session_start();
$_SESSION['DIST']=$str2;

Any help is appreciated!

Answer 1

You can use $_GET to pass a variable through the URL. Then rewrite

www.mysite.com/link.php?redirect_url=100

To

www.mysite.com/100/link.php

Using .htaccess

RewriteEngine on
RewriteRule ^([0-9]*)/link.php$ link.php?redirect_url=$1
