I’m doing a plugin that display another page content for some customer personalization.

With this code:

add_action('template_redirect','hooker');
function hooker(){
        global $post;
        global $wp_query;

        $redirect_post = get_post_meta($post->ID, 'redirect_url_customization', true);
        if(!empty($redirect_post)){
                $post = get_page($redirect_post);

                $content = apply_filters('the_content', $post->post_content);
                echo $content;    
        }else{

        }
}

But the problem is that is showed original page and personalized page. Is it possible to stop to execute the_content()?

Thanks,
Jacopo
