Exception

Description

ArgumentException

An attempt was made to set the ExtendedProtectionSelectorDelegate property, but the CustomChannelBinding property must be a null reference (Nothing in Visual Basic).

ArgumentNullException

An attempt was made to set the ExtendedProtectionSelectorDelegate property to a null reference (Nothing in Visual Basic).

InvalidOperationException

An attempt was made to set the ExtendedProtectionSelectorDelegate property after the Start method was already called.

ObjectDisposedException

This object is closed.

The ExtendedProtectionPolicy property is used with integrated Windows authentication to provide extended protection. The ExtendedProtectionPolicy property allows the configuration of the extended protection policy for the whole HttpListener session. The ExtendedProtectionSelectorDelegate property allows the configuration of the extended protection policy per individual request.

The CustomChannelBinding property must be a null reference (Nothing in Visual Basic). The HttpListener instance gets the Channel Binding Token (CBT) directly from its own TLS session if there is one.

For each request, the delegate can choose the settings that the HttpListener instance will use to provide extended protection.

If a delegate returns a null reference (Nothing in Visual Basic) for this property, this represents a ExtendedProtectionPolicy which the PolicyEnforcement property set to Never.
