What is the correct way to write a RewriteRule for .htaccess?

Question

Apache HTTP Server

I'm not sure if this is actually possible, but the problem is this:
There is a website, let's say example.com
There is a certain module that works on example.com/foo/index.php
Accordingly, there are various URLs like example.com /foo/bar/far , which should all be handled by example.com/foo/index.php
You have the following .htaccess

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . index.php

And everything is fine as long as this module works in the root ( http://example.com)
The problem is that inside the module in the links all URLs look like this: Is it possible to somehow
<a href="/bar/far">Test link</a>
get rid of this by RewriteRule or do I need to change all links in code to /foo/bar/far so that /bar/far "arrives" in index.php?

Answer 1

You understand that a link like /bar/far has nothing to do with the foo module, right? It leads to the root of the site. In any case, you need to change links.
