Configuration (BasicOptions)

Realm

Required to be set if SuppressWWWAuthenticateHeader is not set to true. It is used with WWW-Authenticate response header when challenging un-authenticated requests.

SuppressWWWAuthenticateHeader

Default value is false.
When set to true, it will NOT return WWW-Authenticate response header when challenging un-authenticated requests.
When set to false, it will return WWW-Authenticate response header when challenging un-authenticated requests.

Events

The object provided by the application to process events raised by the basic authentication middleware.
The application may implement the interface fully, or it may create an instance of BasicEvents and assign delegates only to the events it wants to process.

• OnValidateCredentials

• OnAuthenticationSucceeded

• OnAuthenticationFailed

• OnHandleChallenge

• OnHandleForbidden
