 Since they are generated per visit, these routes can be customized for each viewer. For example, a page rendered on demand can show a logged-in user their account information or display freshly updated data without requiring a full-site rebuild. On-demand rendering on the server at request time is also known as **server-side rendering (SSR)**.
