[wp-hackers] WP_Rewrite without query var

[Chris McCoy]

Im trying to rewrite a long file url to a shorter one.

Basically I have zips in a plugin folder I want to rewrite to
/downloads/filename.zip instead of
/wp-content/plugins/plugin-name/zips/filename.zip

Cant figure what im doing wrong.

Here is what I have 

define('ZT_URL', plugins_url('zips/' , __FILE__));

add_action('generate_rewrite_rules', 'cmm_add_rewrite_rules');

function cmm_add_rewrite_rules( $wp_rewrite ) {
        $new_rules = array(
                "^downloads/(.+)\.zip$" => ZT_URL .
$wp_rewrite->preg_index(1)
        );
        $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}

add_action('init','cmm_flush_rules');

function cmm_flush_rules(){
        global $wp_rewrite;
        $wp_rewrite->flush_rules();
}

Any input is greatful.
