URL Rewriting Not Working. Please Help

[eluser]FutureKing[/eluser]
Hi,

I am developing a small blog like application. This is my first time with php frameworks and first time with Codeigniter.
Problem is I am not able to remove index.php from urls.
This is my .htaccess file
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

But I get 404 error when I open http://localhost/contman/postnew/
The page works fine if I open http://localhost/index.php/contman/postnew/

It seems that mod_rewrite is enabled in server(my local system server)

Please help

Unless index.php is located at the root of your server, I would get rid of that leading forward-slash.

/index.php/$1 to index.php/$1

I had the same problem just over a week ago and here's what fixed it for me:

Edit application/config/config.php and find this line

$config[‘uri_protocol’] = "AUTO";

Experiment with the other settings provided in the comments. The one which worked for me was "REQUEST_URI".
