Darn. Okay that hinders testing a bit.

The groups are attached to credentials which are attached to the TCP
connection (TTL only as long as the connection is open) and a token
replay cache for up to authenticate_ttl directive time (default 1 hour).
Setting that TTL to something very short, eg:
authenticate_ttl 10 seconds
... and disabling connection keep-alive:
... should work around the cache for testing. At least on HTTP traffic.
HTTPS traffic goes through the proxy as a single tunnel request - so the
entire HTTPS session is just one request/response pair to Squid.
