CodeIgniter - 如何从URL隐藏index.php

Question

This is what my .htaccess looks like. The .htaccess is sitting in /www/scripts directory which is the parent of codeigniter's system directory and which also contains index.php. I have enabled mod_rewrite in my Apache 2.2.x. This is on Ubuntu 9.10 server.

I followed this link, but it does not work. Is there anything I need to do in apache2, any specific configuration so that this works?

RewriteEngine on 
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$ index.php/$1 [QSA,L]

Answer 1

use this:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /folder/index.php/$1 [L]
