Chrome 6: Server Push Events with new EventSource()

This is mighty awesome. I’ve put together some test demos, to run them you’ll first need to get this Chromium build:

• 47357 WIN32
• 47357 MAC
• 47357 32-Bit Linux
• 47357 32-Bit Linux

Then download these:

For something (only slightly) more involved

http://gist.github.com/415294

Both examples can be found here: http://code.bocoup.com/event-source/event-source-1.html http://code.bocoup.com/event-source/event-source-2.html

They have only been tested in a Chromium nightly and definitely don’t work in FireFox. Be sure to have the javascript console open when running these in order to see the output.

EDIT

In the comments below, there is some interesting info about how this is actually implemented, most notably the comment left by obigid and my reply to them.
