AuthPersistence
The AuthPersistence property specifies authentication persistence across requests on a connection using NTLM authentication.
**[IIS 6.0]**When the AuthPersistSingleRequest flag is set to true when using NTLM authentication, IIS 6.0 automatically reauthenticates every request, even those on the same connection. (Reauthenticating every request also occurs on all other authentication schemes.)
**[IIS 5.0][IIS 5.1]**On IIS 5.0 and IIS 5.1, there are two other flags for the AuthPersistence property specifying persistence based on the existence of a proxy server.
