Hi!
I have an issue with the accel mode in front of an exchange server. When you \
configure more than one authentication scheme including the basic scheme the \
authentication does not work - connection will be closed. But when you configure the \
basic scheme only is starts working. When you have configured more authentication \
schemes it looks like the exchange autodiscover tries which authentication scheme is \
the right one - gets back the HTTP Status 200 for basic scheme and for all others 401 \
and the last connection/session is not for basic scheme so it gets answered with 401 \
and squid is closing the server side and after detecting a "half closed" connection \
squid is also closing the client side. Also the "cache_peer" parameter \
"connection-auth=on" changes nothing.

Thanks in advance for your answer
