Using Url Manager

I want to use URL manager in one of my YII project , I have enabled the URL manager component in main.php




I have also added the .htaccess file under my document root , which contains the following rule

Options +FollowSymLinks

IndexIgnore /

RewriteEngine on

if a directory or a file exists, use it directly

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

otherwise forward it to index.php

RewriteRule . index.php

Now if I try to open an URL such as , nothing happens , the user remains on the home page only , can any one help me out. due to some unknown reasons I am not able to highlight the code .
