TIdOnAuthorization is an event type signalled when an HTTP client connection needs to provide authentication data as part of an HTTP request. TIdOnAuthorization is the event type signalled to the TIdHTTP.OnAuthorization property.

VUserName and VPassword are the authentication credentials found in the HTTP request, and can be updated by the TIdOnAuthorization event handler. Handled indicates if the event handler has successfully authenticated using the client account credentials and method.

TIdOnAuthorization is used after a TIdOnSelectAuthorization event has been signalled to select and create the authentication method for the HTTP client.
