Do you know what/how Firebase is doing the realtime updates? Websockets with fallback to flash?
We use a mix of different methods to maintain a connection. We normally start with our custom long polling implementation and move to websockets when they are available. We do not currently make use of any flash sockets.
It states so on the sites/GH pages, but could not find pointers to repo [after 2 circle through 5 different pages poiting to each other].
