Server-Sent Events (EventSource)
Enables push notifications from the server received as DOM events.

Dear IE team, thank you for the strides you have been making.
WebSockets are overkill in most cases. Please develop support for server-sent events. IE (and Opera Mini, if that even counts) is the only hold-out:
The world is doing de revolution with HTML5 but IE NOT.
You need run to make the best IE
I love IE, please support SSE!

Support Server-Sent Event already *********!
Off-topic: I hope Surface 2 RT can run Windows 10 universal apps or else... How come Surface 2 won't be upgraded to Windows 10? It's a fantastic tablet much better than the iPads and (buggy) Androids
IE is so behind other browsers!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I can't move my app to IE until this is done.
This is a standard that has been in the pipeline since 2009. Given its simplicity and wide-spread adoption by other browsers I would define this as borderline inexcusable.

IE is the only browser that does not support event source: http://caniuse.com/#search=eventsource
The Server-Sent Events solution is lighter than Web Sockets and more proxy and Firewall friendly
A good article about it:

As I already have mentioned before via Tweeter, EventSource is much better to handle in a network environment, since as a sysadmin, proxy servers tend to blow up almost any websocket impl. Server Side Events then, using plain HTTP, looks like a good solution when considering signals from server to the user. The other signal we already have (and working for years), which is the protocol client request itself :)

ASP.net SignalR support this, but IE not.
