WSFederationAuthenticationModule.IsSignInResponse Method (HttpRequestBase)
Gets a value that indicates whether the specified request is a WS-Federation sign-in response message.
Assembly: System.IdentityModel.Services (in System.IdentityModel.Services.dll)
This method is called from the CanReadSignInResponse method in the request processing pipeline to determine whether the incoming HTTP request is a WS-Federation sign-in response message.
The default implementation returns true if the wa parameter is “wsignin1.0” and the wreq and wreqptr parameters are not both set.
You can override this method in derived classes to perform additional validation.
