Authorization.ConnectionGroupId Property


Gets a unique identifier for user-specific connections.

Namespace:   System.Net
Assembly:  System (in System.dll)

Public ReadOnly Property ConnectionGroupId As String

Property Value

Type: System.String

A unique string that associates a connection with an authenticating entity.

The ConnectionGroupId property is a unique string that associates a connection with a specific authenticating entity. For example, the NTLM authorization module ties the authentication credential information to a specific connection to prevent invalid reuse of the connection.

The following code example uses the ConnectionGroupId property to get the group identifier returned by the server. For a complete example, refer to the AuthenticationManager class.

' Create the encrypted string according to the Basic authentication format as
' follows:
' a)Concatenate the username and password separated by colon;
' b)Apply ASCII encoding to obtain a stream of bytes;
' c)Apply Base64 encoding to this array of bytes to obtain the encoded 
' authorization.
Dim BasicEncrypt As String = MyCreds.UserName + ":" + MyCreds.Password

Dim BasicToken As String = "Basic " + Convert.ToBase64String(ASCII.GetBytes(BasicEncrypt))

' Create an Authorization object using the encoded authorization above.
Dim resourceAuthorization As New Authorization(BasicToken)

' Get the Message property, which contains the authorization string that the 
' client returns to the server when accessing protected resources.
Console.WriteLine(ControlChars.Lf + " Authorization Message:{0}", resourceAuthorization.Message)

' Get the Complete property, which is set to true when the authentication process 
' between the client and the server is finished.
Console.WriteLine(ControlChars.Lf + " Authorization Complete:{0}", resourceAuthorization.Complete)

Console.WriteLine(ControlChars.Lf + " Authorization ConnectionGroupId:{0}", resourceAuthorization.ConnectionGroupId)
