throttle/limit a logged in user's http requests to specific page on a per day basis

Question

I have a resource on my WordPress page that I only want to show X times per day per logged in user. I'm using the twenty sixteen WordPress theme.

Currently, Guests / visitors / non logged in users are forced via redirects to authenticate to my site in order to access any content.

How do impose a http request limit / pageview limit on a per-logged-in-user per day or per hour basis? I don't want to do it by IP address, I want to do it by unique user.

Has anyone seen this done? The closet I've seen is : https://premium.wpmudev.org/forums/topic/technical-question-how-to-limit-the-number-of-page-views-for-a-specific-site-under-a-wpmu-instsall#post-384060 but is there a solution already for this? I've searched for throttle, page view, http , limit, restrict, expire, but nothing seems to be restricting content on a logged-in-user-per-day-basis.

Thank you

**UPDATE: I am overriding the default page.php file of twenty sixteen theme to implement basic page-view limiting for logged-in users. **

   <?php

//First, check for get_current_user_id.

$current_user = wp_get_current_user(); if ( 0 == $current_user->ID ) { // Logged out } else { // Logged in.

    //Then create a log of visits by adding information to a user's metadata with update_user_meta & get_user_meta. 

    $COUNT_VISITS_TOTAL_LIMIT = 20;
    $countVisitsUsed = 0;

    if (get_user_meta($current_user->ID, 'countVisitsUsed', true)) {
        $countVisitsUsed = get_user_meta($current_user->ID,'countVisitsUsed',true);
        update_user_meta($current_user->ID, 'countVisitsUsed', $countVisitsUsed+1); //increment
    }else{
          update_user_meta( $current_user->ID, 'countVisitsUsed', 1, false );
          $countVisitsUsed = get_user_meta($current_user->ID,'countVisitsUsed',true);
    }


    if ($countVisitsUsed == null || $countVisitsUsed ==false || $countVisitsUsed < $COUNT_VISITS_TOTAL_LIMIT) { //allow page load



        //start of page.php

            /**

First, check for get_current_user_id. Then create a log of visits by adding information to a user's metadata with update_user_meta & get_user_meta.

On every page hit that you care about you can run a function to determine rate/limit of usage per user.

If they break the rules, you can redirect to a page that doesn't contain that logic with wp_redirect.
