I have a page page_x where content is created by a callback function mycallback_1()
This function retrieves data from an external source with PHP cURL. This data is updated frequently, every 2-4 hours.
So in general it would not be neccessary to call mycallback_1() (and cURl) on every page view. I'm not sure if and how Xenforo caches pages. Can I do this? Let's say can I cache page_x for half an hour within the xenforo system (maybe with a setting in setting.php) ?
