Take the 2-minute tour ×  I've been watching the "Network"
section in the Chrome developer tools to see what activity there
is on a new and active post here at Stackoverflow.  I expected
to see periodic network activity to check a script for updated
elements on the page (such as new comment or answer posted) -
But there doesn't appear to be one!  I just implemented a
periodic "heartbeat" for some pages on my site.  Does
Stackoverflow achieve some sort of "push" check for new posts?
share|improve this question I assumed it was done via sockets.

after looking around I found these two very useful links:    1.
How do real time updates work?    2. Periodic Pull - Comet (Long
Polling) - WebSockets  share|improve this answer run into the
same problem here... the second link is broken but the first one
is good enough, thanks! –
