I believe it's a continuation-style server—hence fnid: function id—and the continuations are only kept around in memory for ~5 minutes.

  I never understood why the continuation couldn't instead be addressed by a URL path. It could even get constructed from URL/query data if it moves out of memory, so keeping them in memory would only be a caching mechanism.

    Yes, but the way hn works, the continuations map uri's to browser sessions so they can be expired on a more granular basis than all at once or lru or what have you. I'm guessing here, though, I've not looked through the code. [addendum] I Reread your comment and realized that wasn't what you meant at all. What would be the benefit of path based uris over query string params in hn's case? I only see how they be equal, not better.

      I meant that the continuation could be identified by (session_id, URL data), and re-created based on this data if it goes missing. URL data can come from path or query string, it doesn't matter.

    Every continuation framework I've looked at radiates an intense desire to treat the web as something other than what it actually is.
