this is my new script with CI
http://wgd.ir
and here is my .httaccess
Options FollowSymLinks
DirectoryIndex index.php
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [NC,L,QSA]
This type of removing index.php is really slow.
