I don't know about long gone. I still support a websocket solution that needs to have server-push as a fallback because of browser incompatibility issues.


It shouldn't be a problem for about a decade [0]?

What's your hit rate for the fallback?

The hit rate for fallback is pretty low. It was less than 5% the last I checked.


This 5% includes or excludes non-human traffic?


Includes.


Do you have some specific examples?


Old Android handsets seem to be the big ones.
