Last time I looked at those they were just using regular HTTP
long-pollinng techniques. Though some may have moved to WebSockets or
Squid does not have to do anything for those. The clients and server
involved do the mapping of their data into various HTTP requests and
replies. So as far as Squid is concerned they are just regular long
duration GET or POST requests. Which since they are HTTP messages can be
passed to the ICAP service in the normal ways.
