If the ProxySG and a client cannot successfully authenticate the use of Kerberos credentials during authentication in a realm where use of Kerberos credentials is
enabled, what happens to the authentication request?
When a downstream ProxySG requests an object that already is cached in an upstream ProxySG, the downstream ProxySG checks the object's freshness with the
origin content server.
If a user agent that does not support authentication tries to request content through a connection on which the ProxySG requires authentication, how can you best
resolve the issue?
