The following code example creates a WebProxy object and calls this method to check whether the bypass list is properly set.
WebProxy^ CreateProxyAndCheckBypass( bool bypassLocal )
{
// Do not use the proxy server for Contoso.com URIs.
array<String^>^ bypassList = {";*.Contoso.com"};
WebProxy^ proxy = gcnew WebProxy( "http://contoso",
bypassLocal,
bypassList );
// Test the bypass list.
if ( !proxy->IsBypassed( gcnew Uri( "http://www.Contoso.com" ) ) )
{
Console::WriteLine( "Bypass not working!" );
return nullptr;
}
else
{
Console::WriteLine( "Bypass is working." );
return proxy;
}
}
public static WebProxy CreateProxyAndCheckBypass(bool bypassLocal)
{
// Do not use the proxy server for Contoso.com URIs.
string[] bypassList = new string[]{";*.Contoso.com"};
WebProxy proxy = new WebProxy("http://contoso",
bypassLocal,
bypassList);
// Test the bypass list.
if (!proxy.IsBypassed(new Uri("http://www.Contoso.com")))
{
Console.WriteLine("Bypass not working!");
return null;

{
Console.WriteLine("Bypass is working.");
return proxy;

Remarks
The IsBypassed method is used to determine whether to bypass the proxy server when accessing an Internet resource.
The BypassProxyOnLocal and BypassList properties control the return value of the IsBypassed method.
IsBypassed returns true
under any of the following conditions:
If BypassProxyOnLocal is
true
andhost
is a local URI. Local requests are identified by the lack of a period (.) in the URI, as inhttp://webserver/
.If
host
matches a regular expression in BypassList.If Address is
null
.
All other conditions return false
.
