How to create such a rule in .htaccess?

Question

Apache HTTP Server

.htaccess:

RewriteEngine On
ErrorDocument 404 /404.html
RewriteRule ^main /index.php
....

I need a handler for a 404 page, let's say this:
User: opens a non-existent https://yoursite.loc/asdasdasdasdas page in the browser
and .htaccess: https://yoursite.loc/404?link= https://yoursite.loc /asdasdasdasdas
Help, if the option to do this is in .htaccess?

Answer 1

and .htaccess: https://yoursite.loc/404?link=https://yoursite.loc...

It is not entirely clear what exactly .htaccess is, but since you have PHP, use and and already build further logic based on them. However, I strongly recommend that you display both of them with the help before starting work and see what these variables contain. If my memory serves me right, the contents can be either the same or different, depending on the specific software environment. $_SERVER['REDIRECT_URL']$_SERVER['REQUEST_URI']
