Understanding mod_rewrite syntax

Question

When I write in .htaccess this mod_rewrite

 RewriteEngine on
 RewriteRule ^(.*)\.my_extension$ $1.php

and open url: site.com/index.my_extension this wroks fine, opened index.php

But when I am trying mod_rewrite like this:

 RewriteEngine on
 RewriteRule ^(.*)$ index.php?url=$1

this gives me Internal Server Error.

Why this happened? what is reason?

You need to add more information. Have you enabled rewrite logging? Are the two rewrite rules in the same config file? It can be possible that you could have a redirect/rewrite loop, as you are catching all then redirecting to index.php?url=foo/bar/index.php?url=foo/bar/index.php, etc. — Danie, Apr 25 '13 at 10:53
1) `Have you enabled rewrite logging?` --- if rewrite logging not enabled, then how firts rewriterule works? 2) `Are the two rewrite rules in the same config file?` --- no, just one RewriteRule is in `.htaccess` file. 3) `It can be possible that you could have a redirect/rewrite loop` --- In other servers, catching all then redirecting to index.php works, and here why must happened redirect/rewrite loop? reason of this may be some option? — Oto Shavadze, Apr 25 '13 at 11:13

RewriteEngine on
RewriteCond %{REQUEST_URI} !(index.php)
RewriteRule ^(.*)$ index.php?url=$1

You have a redirect loop, you need to exclude index.php from the rules.
