Public Property StatusDescription As String

Property Value

Type: System.String

The text description of the HTTP status code returned to the client. The default is the RFC 2616 description for the StatusCode property value, or an empty string ("") if an RFC 2616 description does not exist.

Exception Condition

The value specified for a set operation is null.


The value specified for a set operation contains non-printable characters.

The status description typically provides details that explain the StatusCode value.

The following code example demonstrates setting the value of this property.

' When the client is not authenticated, there is no Identity.
If context.User Is Nothing Then
    message.Append("<HTML><BODY><p> Hello local user! </p></BODY></HTML>")
    ' Get the requester's identity.
    Dim identity As System.Security.Principal.WindowsIdentity = WindowsIdentity.GetCurrent()
    ' Construct the response body.
    message.AppendFormat("<HTML><BODY><p> Hello {0}!<br/>", identity.Name)
    message.AppendFormat("You were authenticated using {0}.</p>", identity.AuthenticationType)
End If

' Configure the response.
Dim response As HttpListenerResponse = context.Response

' Use the encoding from the response if one has been set.
' Otherwise, use UTF8.
Dim encoding As System.Text.Encoding = response.ContentEncoding
If encoding Is Nothing Then
    encoding = System.Text.Encoding.UTF8
    response.ContentEncoding = encoding
End If
Dim buffer() As Byte = encoding.GetBytes(message.ToString())
response.ContentLength64 = buffer.Length
response.StatusCode = CInt(HttpStatusCode.OK)
response.StatusDescription = "OK"
response.ProtocolVersion = New Version("1.1")
' Don't keep the TCP connection alive
' We don't expect multiple requests from the same client.
response.KeepAlive = False
' Write the response body.
Dim stream As System.IO.Stream = response.OutputStream
stream.Write(buffer, 0, buffer.Length)
