How do I setup CodeIgniter htaccess in a sub-folder?
===

I have setup a CodeIgniter Application on my server at the following URL:+

    http://subdomain.domainame.com/something1/something2/
(I have used something1 and something 2 as examples)

Now, I can access the application perfectly fine when using the above URL and can add /index.php/controller/action etc to the end.

I have tried to setup a .htaccess file in the same directory the application is hosted but it doesn't seem to be working. 

The .htaccess file contains the following:

    RewriteEngine on
    RewriteCond $1 !^(index\.php|images|robots\.txt)
    RewriteRule ^(.*)$ something1/something2/index.php?/$1 [L]

This is giving me a 500 Internal Server Error.

Can anyone shed some light on this?
