BasicHttpBinding.BypassProxyOnLocal Property

Gets or sets a value that indicates whether to bypass the proxy server for local addresses.

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

public bool BypassProxyOnLocal { get; set; }

Property Value

Type: System.Boolean
true to bypass the proxy server for local addresses; otherwise, false. The default value is false.

An Internet resource is local if it has a local address. A local address is one that is on same computer, the local LAN or intranet and is identified, syntactically, by the lack of a period (.) as in the URIs "http://webserver/" and "http://localhost/".

Setting the BypassProxyOnLocal property determines whether endpoints configured with the BasicHttpBinding use the proxy server when accessing local resources.

If BypassProxyOnLocal is true, requests to local Internet resources do not use the proxy server. Use the host name (rather than localhost) if you want clients to go through a proxy when talking to services on the same machine when this property is set to true.

When BypassProxyOnLocal is false, all Internet requests to non-localhost URIs are made through the proxy server. Requests to URIs with localhost will not use the proxy server regardless of the BypassProxyOnLocal setting.


The following example sets this property to indicate that the proxy should be bypassed for local resources.

            BasicHttpBinding binding = new BasicHttpBinding();
	    binding.BypassProxyOnLocal = true;

The value of this property can also be set in the configuration file.
