<defaultProxy

/>

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Element	Description
enabled	Specifies whether a web proxy is used. The default value is true.
useDefaultCredentials	Specifies whether the default credentials for this host are used to access the web proxy. The default value is false.

Child Elements

Element	Description
bypasslist	Provides a set of regular expressions that describe addresses that do not use the proxy.
module	Adds a new proxy module to the application.
proxy	Defines a proxy server.

Parent Elements

Element	Description
system.net	Contains settings that specify how the .NET Framework connects to the network.

Remarks

If the defaultProxy element is empty, the proxy settings from Internet Explorer will be used. This behavior is different from version 1.1 of the .NET Framework.

Configuration Files

This element can be used in the application configuration file or the machine configuration file (Machine.config).

Example

The following code example uses the defaults from the Internet Explorer proxy, specifies the proxy address, and bypasses the proxy for local access and contoso.com.

<configuration>
  <system.net>
    <defaultProxy>
      <proxy
        usesystemdefaults="true"
        proxyaddress="http://192.168.1.10:3128"
        bypassonlocal="true"
      />
      <bypasslist
        <add address="[a-z]+\.contoso\.com" />
      </bypasslist>
    </defaultProxy>
  </system.net>
</configuration>
