How does `?max_posts=1` work?

(Jan P.) #1

I found out about adding ?max_posts=1 to the end of URLs (/latest, /new) to filter the topics to only unanswered ones. But it seems this somehow has strange side effects. Even when I click on “New” again and then land on a plain /new, without the params, I don’t see the topics with more than 1 post. Is ?max_posts=1 saved to my session somehow?
