Ejemplos
En el ejemplo de código siguiente se obtiene o establece el prefijo para los URI que se pueden autenticar con la Message propiedad .
public Authorization Authenticate( string challenge,WebRequest request,ICredentials credentials)
{
try
{
string message;
// Check if Challenge string was raised by a site which requires 'CloneBasic' authentication.
if ((challenge == null) || (!challenge.StartsWith("CloneBasic")))
return null;
NetworkCredential myCredentials;
if (credentials is CredentialCache)
{
myCredentials = credentials.GetCredential(request.RequestUri,"CloneBasic");
if (myCredentials == null)
return null;
}
else
{
myCredentials = (NetworkCredential)credentials;
}
// Message encryption scheme :
// a)Concatenate username and password seperated by space;
// b)Apply ASCII encoding to obtain a stream of bytes;
// c)Apply Base64 Encoding to this array of bytes to obtain our encoded authorization message.
message = myCredentials.UserName + " " + myCredentials.Password;
// Apply AsciiEncoding to 'message' string to obtain it as an array of bytes.
Encoding ascii = Encoding.ASCII;

Comentarios
La ProtectionRealm propiedad contiene una lista de prefijos de URI que la Message propiedad se puede usar para autenticarse. WebRequest y sus descendientes comparan un URI con esta lista para determinar si es Authorization válido para un URI determinado.
