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 |
|---|---|
Configures the Hypertext Transfer Protocol (HTTP) proxy server. |
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.
An exception is thrown if the proxyaddress attribute specifies an invalid default proxy. The InnerException property on the exception should have more information about the root cause of the error.
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>
