If you want to make Drupal server (themed) pages, it is pretty straight forward, but what if you want it to serve small chunks of data (e.g. as JSON).
I’d like to have parts of my page load asynchronously, e.g. a block that refreshes every 10′ with the active users.
What is the proper way to go about it in Drupal?
