Forum caching very confusing
As I think this is a larger issue (in comparison with the others that are only listed on the forum itself), I'm making a proper report for this now.
Caching for the forum results in differing numbers / outdated page content on all pages.
Forum list: wrong display of unread message number
Topic list: wrong highlighting for unread, wrong last-post-dates
Comment list: wrong display of post time, missing comments
etc.
Which page you get (outdated, or up-to-date, or less outdated) depends on the link you click on, not on browser cache.
Made a short video, more for the fun of it (as I'm sure you can reproduce this).
