title: Bind a single wordpress page to single endpoint
body: <p>Asked this on the WordPress StackExchange but it was considered a generic PHP/JS/SQL/HTML/CSS question and closed. So therefore I'm here.</p>
  <p>On a Wordpress multisite I'm trying to bind the content of a custom post type from a sub site to a single endpoint.</p>
  <p>More specifically, I want</p>
  <p><a href="https://sub.example.com/custom_post_type/content" rel="nofollow noreferrer">https://sub.example.com/custom_post_type/content</a></p>
  <p>to be opened only from 1 specific endpoint. If the user tries to open it from another endpoint (physical device, other browser on same machine),request is redirected somewhere.</p>
  <p>I'm sure this can be done, but how? Some kind of token / otp? Any suggestion would be really appreciated!</p>
