Not that I ever heard of.

HTTP contains nothing such as a 'session'. So normal auth is sent on
every single request.

NTLM gets around that by authenticating not the request, but the TCP
link itself. You cannot have two servers and a client on the same link.

You can do NTLM auth on both squid though, and have the user
authenticate with whichever one its trying to use at the time.

keep-alive + persistent connections also come into play to keep a whole
series of requests from client to a single squid going down the same
authenticated link.
