<defaultProxy> Element (Network Settings)
Configures the Hypertext Transfer Protocol (HTTP) proxy server.
<configuration>
<system.net>
<defaultProxy>
Syntax
<defaultProxy
enabled="true|false"
useDefaultCredentials="true|false"
<bypasslist> … </bypasslist>
<proxy> … </proxy>
<module> … </module>
/> 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.
An exception is thrown if the module element specifies a non-public type, the type is not deriving from the xref:System.Net.IWebProxy class, an exception from the default constructor of this object occurred, or an exception occurred while retrieving the system-specified default proxy. The xref:System.Exception.InnerException%2A 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 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
usesystemdefault="true"
proxyaddress="http://192.168.1.10:3128"
bypassonlocal="true"
/>
<bypasslist>
<add address="[a-z]+\.contoso\.com" />
</bypasslist>
</defaultProxy>
</system.net>
