Is there a Microsoft equivalent for HTML5 Server-Sent Events?
Solution 1:
In a word, no.
Microsoft has not included SSE or an equivalent of SSE in any version of IE. IMO, you have two good options:
-
Use a polyfill - My tests with this polyfill in IE10 and IE11 were all successful. Since it starts with
if ("EventSource" in global) return;, it'll only run in browsers that do not supportEventSource. -
Use websockets instead - Although it requires more server-side setup (The
ws://protocol), it works in IE10 and 11 and provides more options such as bi-directional communication.
Solution 2:
SSE native support for IE is not there. You can achieve same thing using polyfill
