Notes

Bugs

  • Reportedly, CORS in EventSource is currently supported in Firefox 10+, Opera 12+, Chrome 26+, Safari 7.0+.

  • In Firefox prior to version 36 server-sent events do not reconnect automatically in case of a connection interrupt (bug)

  • Firefox 52 and below do not support EventSource in web/shared workers

  • Antivirus software may block the event streaming data chunks.
