The following code example creates a new instance of the Authorization class with the specified authorization message, completion status, and connection group identifier.

Public Function Authenticate(challenge As String, request As WebRequest, credentials As ICredentials) As Authorization Implements IAuthenticationModule.Authenticate
        Dim message As String 
        ' Check if Challenge string was raised by a site which requires CloneBasic authentication. 
        If challenge Is Nothing Or Not challenge.StartsWith("CloneBasic") Then 
            Return Nothing 
        End If 
        Dim myCredentials As NetworkCredential
        If TypeOf credentials Is CredentialCache Then
            myCredentials = credentials.GetCredential(request.RequestUri, "CloneBasic")
            If myCredentials Is Nothing Then 
                Return Nothing 
            End If 
            myCredentials = CType(credentials, NetworkCredential)
        End If '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 our user name and password to obtain it as an array of bytes 
        Dim asciiEncoding As Encoding = Encoding.ASCII
        Dim byteArray(asciiEncoding.GetByteCount(message)) As Byte

        '         *that  we just formed and it also sets the 'Complete' property to true and the connection group id 
        '         *to the domain of the NetworkCredential object 
        Dim myAuthorization As New Authorization("CloneBasic " + message, True, request.ConnectionGroupName)
        Return myAuthorization
