Gets or sets a query string that contains any additional parameters to be sent in WS-Federation sign-in requests (“wsignin1.0”).
Assembly: System.IdentityModel.Services (in System.IdentityModel.Services.dll)
An attempt to set the property to a null reference (Nothing in Visual Basic) occurs.
You can use this property to send additional parameters in a sign-in request. These would be application-specific parameters that are not one of the parameters that are specified by the WS-Federation protocol. To remove additional parameters from the request set the property to an empty string.
You can override this setting on each HTTP request by adding a handler for the RedirectingToIdentityProvider event. This event is raised just before the module redirects to the security token service (STS) with a WS-Federation sign-in request message. The STS is specified by the Issuer property.
