[google-appengine] Server Sent Events in GAE Standard
I need to send messages from the Web server to a browser based application. Server Sent Events are an obvious choice but I cannot see any supporting documentation. Is it possible to do this with GAE standard using Java 8 ? If not, is there a way to run web sockets, or some other technology that will allow messages to be sent to the browser. I don't want to resort to polling from the browser. Thanks, Steve. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Server Sent Events in GAE standard environment - ADVICE PLEASE
I need to be able send notifications to a web application from the app engine server. For me Server Sent Events seem to be the best option. However, I cannot find any supporting docs for this in GAE standard environment (Java 8). Is this feature implemented at all in GAE? Is there something else I should be looking for? web sockets are another possibility for me, but from what I can tell, they aren't supported.

Yes it is a duplicate - I hadn't realised the group was moderated and didn't see my first attempt to post a question listed and tried again. There doesn't seem to be a way to delete this post either. If someone has privileges to delete it, then please do.

Thanks for the advice - I'll add a comment to this pwhen I've had a chance to try Server Side Events.
