.htaccess and routing

[eluser]ibnclaudius[/eluser]
I want to send the parameter like:

http://localhost/index.php/myparameter

so I made this routing:

Code:

$route['(:any)'] = 'events/event/$1';

cause my main controller is something like:

Code:

class Events extends CI_Controller {

    public function index()
    {}

    public function event()
    {}

}

until this point everything works, but the error starts when trying to remove the index.php from the url, by creating this .htaccess:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

and removing the index.php from:

Code:

$config['index_page'] = 'index.php';

but when I try to access an url like http://localhost/myparameter I get a not found! :S And yes, mod_rewrite is enabled!
