You may want to check out the rproxy enhancement project:
        http://squid.sourceforge.net/rproxy/

The sticky load balancing is apparently done (based on IP).

It handles a downed server very quickly (no more than a few seconds). Out
of the box, it has trouble with up, but floundering, servers. A low
connect timeout or a health check query (also done in the rproxy patch)
will improve that case.

It usually takes about a minute for squid to detect a recovered server.
