Gets or sets a Boolean value that specifies whether your application receives exceptions that occur when an HttpListener sends the response to the client.

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

Public Property IgnoreWriteExceptions As Boolean

Property Value

Type: System.Boolean
true if this HttpListener should not return exceptions that occur when sending the response to the client; otherwise false. The default value is false.


This object has been closed.

Set this property to true if your application does not require that a response is successfully sent to each client.

The following code example demonstrates setting this property.

Public Shared Sub SimpleListenerWithUnsafeAuthentication(ByVal prefixes() As String)
    ' URI prefixes are required,
    ' for example "http://contoso.com:8080/index/".
    If prefixes Is Nothing OrElse prefixes.Length = 0 Then
        Throw New ArgumentException("prefixes")
    End If
    ' Set up a listener.
    Dim listener As New HttpListener()
    For Each s As String In prefixes
    Next s
    ' Specify Negotiate as the authentication scheme.
    listener.AuthenticationSchemes = AuthenticationSchemes.Negotiate
    ' If NTLM is used, we will allow multiple requests on the same
    ' connection to use the authentication information of first request.
    ' This improves performance but does reduce the security of your 
    ' application. 
    listener.UnsafeConnectionNtlmAuthentication = True
    ' This listener does not want to receive exceptions 
    ' that occur when sending the response to the client.
    listener.IgnoreWriteExceptions = True
    ' ... process requests here.
