How to write rewrites for an Instagram-like service?

Question

Apache HTTP Server

Hey! the essence is the following:
mod_rewrite.
http://site.com/& http://site.comshould redirect to site.com/index.php
BUT http://site.com/aeiu3bx(i.e. ([A-Za-z0-9#]+)) should redirect to site.com/index.php?param=$1

There are rules like this:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.*)$ index.php?param=$1 [L]

and they don't work properly.
More precisely, only the last rule works - site.com/o3unxo3-> site.com/index.php?param=o3unxo3,
but it site.com/turns into some kind of mess of paths like site.com/home/var/www/site.com/site.com/

How to be???? 6 years ago I myself did such a thing on some forum in the answers, but I rubbed everything and I can’t find it by God) and formulate it for Google too

Answer 1

those rewrites that you showed here work great
and for the voiced tasks of this code, a
sausage with a root request is enough - this is the code that you don’t show us,
so you need to throw out the rest of the code responsible for rewrites and redirects, and everything will work
