how does phpbb3 autorefresh on browser backstep?

One thing that strikes me as pretty cool is that when you start on viewforum, click to open a topic and then use the browser backstep button to go back to viewforum, phpbb3 refreshes the viewforum page so that you can see whatever changes may have occurred in the topic list (and unread flag status) since when you clicked into the topic.

How does phpbb3 tell the browser to do that?

With "cache-control", "no-cache" and "no-store".
You can google for tutorials on their use. Header function in PHP Manual.

These tags are used in various specific places in the phpBB software. Note that the client (the user's browser) can probably be configured to ignore those tags.
