compatible?

Hi,

I use hyper cache for 4 small sites and i’m a fan of this plugin!
Now i would like to use hypercache but my server runs nginx.There is any problem because i read some posts for compatibility problems.
Also i use this code for pupular posts. With other plugins i used fragment cache but this IS NOT cache 😛

function wpb_set_post_views($postID) {
    $count_key = 'wpb_post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
//To keep the count accurate, lets get rid of prefetching
remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0);

function wpb_track_post_views ($post_id) {
    if ( !is_single() ) return;
    if ( empty ( $post_id) ) {
        global $post;
        $post_id = $post->ID;
    }
    wpb_set_post_views($post_id);
}
add_action( 'wp_head', 'wpb_track_post_views');

Of i switch to hypercache what changes i must do to track popular posts?
I have 45.210 posts.
I’ll have a problem or no?

Thanks,
Yannis
