Facebook uses something they call BigPipe, which splits the page up into a bunch of little "pagelets" that are individually loaded via AJAX.

In the image below, the areas highlighted in light-blue are individual pagelets.

To be clear - they are not loaded by ajax. all the pipes are loaded from one response. – zerkms Nov 08 '10 at 01:33
Initially. After load, though, updates are being pulled in dynamically. – ceejayoz Nov 08 '10 at 02:01
yes. but the main idea in BigPipe is that all the contents is loaded with one request. Also, to be precise - the data after the initial loading is being loaded with Comet. – zerkms Nov 08 '10 at 02:25
not just js after loading full page new pages are loaded by iframe. ie. loading profile of a friend uses iframe. – Waqar Alamgir Feb 15 '13 at 07:31
I doubt they're using iframes. – ceejayoz Feb 15 '13 at 14:36
