Attributes and Elements

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

Attributes

Attribute	Description
autoDetect	Specifies whether the proxy is automatically detected. The default value is unspecified.
bypassonlocal	Specifies whether the proxy is bypassed for local resources. Local resources include the local server (https://localhost, https://loopback, or http://127.0.0.1) and a URI without a period (http://webserver). The default value is unspecified.
proxyaddress	Specifies the proxy URI to use.
scriptLocation	Specifies the location of the configuration script.
usesystemdefault	Specifies whether to use Internet Explorer proxy settings. If set to true, subsequent attributes will override Internet Explorer proxy settings. The default value is unspecified.

Child Elements

None.

Parent Elements

Element	Description
defaultProxy	Configures the Hypertext Transfer Protocol (HTTP) proxy server.

Text Value

Remarks

The proxy element defines a proxy server for an application. If this element is missing from the configuration file, then the .NET Framework will use the proxy settings in Internet Explorer.

The value for the proxyaddress attribute should be a well-formed Uniform Resource Indicator (URI).

The scriptLocation attribute refers to the automatic detection of proxy configuration scripts. The WebProxy class will attempt to locate a configuration script (usually named Wpad.dat) when the Use automatic configuration script option is selected in Internet Explorer.

Use the usesystemdefault attribute for .NET Framework version 1.1 applications that are migrating to version 2.0.

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.

<configuration>
  <system.net>
    <defaultProxy>
      <proxy
        usesystemdefault="true"
        proxyaddress="http://192.168.1.10:3128"
        bypassonlocal="true"
      />
    </defaultProxy>
  </system.net>
</configuration>
