Segmented Rendering is just a smarter way to do static rendering. Once you understand that it’s all about caching renders and then getting the right cached render for each request, everything will click into place.

To implement segmented rendering:

1. Define your “segments” for a page.
   Example: paid users versus free users, users from company A versus users from company B or C, etc.
2. Render as many static variations of a page you need, with one URL per segment.
   Example: /with-jokes/my-article, /bland/my-article. Each variation matches a segment, for instance, paid or free users.
3. Setup a very small redirection server, that checks the HTTP request content and redirects the user to the right variation, depending on their segment. Example: paid users are redirected to /with-jokes/my-article. We can tell if a user is paid or not by checking their request cookies.
