AuthPersistence
The AuthPersistence property specifies authentication persistence across requests on a connection using NTLM authentication. When the AuthPersistSingleRequest flag is set to true on this property, and on all other authentication schemes, IIS 6.0 automatically reauthenticates every request, even those on the same connection. This behavior is different on IIS 5.0 and IIS 5.1, where there were two other flags for the AuthPersistence property specifying persistence based on the existence of a proxy server.
