The content on that page is updated every time it’s loaded. For example, look at the Suggested Topics section.

A Last-Modified header is not part of the discourse API. It’s a recommendation to the web browser (to be used in conjunction with the Cache-Control header) that the page being requested is dynamic content and should not be cached.

That is how [HTTP caching works](https://developer.mozilla.org/en-US/docs/Web/HTTP/Caching).
