Removing index.php in Codeigniter

[eluser]faisal_memon[/eluser]
I am not able to remove index.php from the url's

http://sitename.com/index.php/controller...ethod-name

I don't want index.php in above url.

Explanation of what I want to achieve : Normally we access a view in codeigniter by

Code:

http://site-name/index.php/controller-name/method-name

I don't want to use index.php in any of my urls. I want url's to be like -

Code:

http://site-name/controller-name/method-name

Here is my .htaccess file

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Submitted by: Fabdrol
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
