Avoid rewrite in folder

[n0ldor]

Hello good morning, first sorry my English.

The question is I have a website where all the links point to. Php does not exist and by htaccess redirects everything to index.php which is in charge of loading as appropriate depending on the URL. To do this use the following:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

Until this point everything is working correctly I only now I just want to do the same for the administration, but the problem I have is that the administration is in a folder called "admin" in the same server, so the htaccess the web I get redirected to index the web.
How could I do to get into the admin folder a different htaccess?
Do you suggest me other way to do this?

thanks

Add a preceding RewriteRule that rewrites ^admin/(.*) URL requests to the /admin/index.php script file.
