IWebProxy.IsBypassed Method

Indicates that the proxy should not be used for the specified host.

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

Function IsBypassed ( _
	host As Uri _
) As Boolean
Dim instance As IWebProxy
Dim host As Uri
Dim returnValue As Boolean

returnValue = instance.IsBypassed(host)
boolean IsBypassed (
	Uri host
function IsBypassed (
	host : Uri
) : boolean



The Uri of the host to check for proxy use.

Return Value

true if the proxy server should not be used for host; otherwise, false.

The IsBypassed method indicates whether to use the proxy server to access the host that is specified in the host parameter. If IsBypassed is true, the proxy is not used to contact the host and the request is passed directly to the server.

The following example uses the IsBypassed property to determine whether the proxy server should be used for the specified host.

Public Shared Sub Main()
    Dim webProxy_Interface As New WebProxy_Interface(New Uri("http://proxy.example.com"))
    webProxy_Interface.Credentials = New NetworkCredential("microsoft", ".Net")
    Console.WriteLine("The web proxy is : {0}", webProxy_Interface.GetProxy(New Uri("http://www.microsoft.com")))
    'Determine whether the Web proxy can be bypassed for the site "http://www.microsoft.com".
console.writeline("For the Uri http://www.microsoft.com , the ")
    If webProxy_Interface.IsBypassed(New Uri("http://www.microsoft.com")) Then
        Console.WriteLine("webproxy is by passed")
        Console.WriteLine("webproxy is not bypassed")
    End If 
End Sub 'Main

WebProxyInterface webProxyInterface = new WebProxyInterface(
    new Uri("http://proxy.server.com"));
webProxyInterface.set_Credentials(new NetworkCredential(
    "microsoft", ".Net"));
Console.WriteLine("The web proxy is : {0}", webProxyInterface.
    GetProxy(new Uri("http://www.microsoft.com")));

// Check if the webproxy can ne bypassed for the site 
if (webProxyInterface.IsBypassed(new Uri(
    "http://www.microsoft.com"))) {
    Console.WriteLine("Web Proxy is by passed");
else {
    Console.WriteLine("Web Proxy is not by passed");
