How to remove index.php from codeigniter 2.0.2

[eluser]mi6crazyheart[/eluser]
Ok!!! i know it's pretty old question & there are a lot of info available on CI forum.. but, i really now in trouble in this particular issue(remove index.php).

I tried out a lot tweaks & tricks available over in forum but yet have not get any luck. Hope, u guys give me some help to figure out this problem.

Here is some info about my dev. enviroement...

OS: ubuntu 10.04 LTS
Done apache 2 mod_rewrite by following this tuto : http://goo.gl/tglai

My .htaccess file

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /http://localhost/vb/

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /vb/index.php?/$1 [L]
    
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /vb/index.php?/$1 [L]

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

vb : Root folder name where i've stored all my codeigniter files

Update my config.php by making following changes
* $config['index_page'] = '';
* $config['uri_protocol'] = 'REQUEST_URI';


I'm using sub-folders to organize my controller files. Don't know, whether this has any links to that .htaccess or not.
