There is no optimization for live streaming without caching.
The Squid collapsed-forwarding feature for splitting single response to
multiple clients relies on responses being cacheable (even if not
stored) so that multiple clients are *allowed* to receive them. Live
streams are usually marked as non-cacheable, and Flash video is even
worse since each stream has different framing intervals depending on
when each client connected with adaptive bitrate frames depending on
each clients individual end-to-end latency.

This assumes the stream is an HTTP data stream. A lot of streams these
days are ICY protocol, even if displayed by a Flash script interpreter.
