my .htaccess file is not working

[eluser]Sumon[/eluser]
hi all,

i develope my site using CodeIgniter and trying to hide url(index.php). Server guys replied me : "Mod_rewrite is enabled for your account". As such i write
a .htaccess file with the following code:

Options +FollowSymLinks
DirectoryIndex index.php
RewriteEngine On
RewriteRule ^.htaccess$ - [F]
RewriteRule ^favicon.ico - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]

Now here is the URL i have tried to browse But not working.

www.mysite.com/home
instead of
www.mysite.com/index.php/home

[ The page display: No input file specified. ]

Is any change needed in config.php file? Please help me to resolve my problem.
