Authorization.ProtectionRealm Property

Gets or sets the prefix for Uniform Resource Identifiers (URIs) that can be authenticated with the Message property.

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

public string[] ProtectionRealm { get; set; }

Property Value

Type: System.String[]
An array of strings that contains URI prefixes.

The ProtectionRealm property contains a list of URI prefixes that the Message property can be used to authenticate. WebRequest and its descendants compare a URI to this list to determine if the Authorization is valid for a particular URI.

The following code example gets or sets the prefix for URIs that can be authenticated with the Message property.

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;
        byte[] byteArray = new byte[ascii.GetByteCount(message)];
        byteArray = ascii.GetBytes(message);

        // Performing Base64 transformation.
        message = Convert.ToBase64String(byteArray);
