Question

what i am trying to do is this:

If url http://example.com/foo/foo.php is called it should be redirected with 301 to http://example.com/bar/foo.php

AND

if url http://example.com/bar/foo.php is called it internally calles the /bar/foo.php script but browser url is not changed (remap).

my rules look like this

RewriteRule ^foo/foo.php(.*) bar/foo.php$1 [R=301]
RewriteRule ^bar/foo.php(.*)$ foo/foo.php$1 [PT]

But this gives me too many redirects error.

Each rule activated separately works but together they seem to conflict…

You can either match against the actual request:

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /foo/foo.php
RewriteRule ^foo/foo.php(.*) bar/foo.php$1 [R=301]
RewriteRule ^bar/foo.php(.*)$ foo/foo.php$1 [L]

Or prevent rewrite looping altogether:

RewriteCond %{ENV:REDIRECT_STATUS} !200
RewriteRule ^foo/foo.php(.*) bar/foo.php$1 [R=301]
RewriteRule ^bar/foo.php(.*)$ foo/foo.php$1 [L]
