Attributes and Elements
The following sections describe attributes, child elements, and parent elements.
Attributes
| Attribute | Description |
|---|---|
| address | A regular expression describing an IP address or DNS name. |
Child Elements
None.
Parent Elements
| Element | Description |
|---|---|
| bypasslist | Provides a set of regular expressions that describe addresses that do not use a proxy. |
Remarks
The add element inserts regular expressions describing IP addresses or DNS server names to the list of addresses that bypass a proxy server.
The value of the address attribute should be a regular expression that describes a set of IP addresses or host names.
You should use caution when specifying a regular expression for this element. The regular expression [a-z]+\\.contoso\\.com matches any host in the contoso.com domain, but it also matches any host in the contoso.com.cpandl.com domain. To match only a host in the contoso.com domain, use an anchor ($): [a-z]+\\.contoso\\.com$.
For more information about regular expressions, see ..NET Framework Regular Expressions.
Configuration Files
This element can be used in the application configuration file or the machine configuration file (Machine.config).
Example
The following example adds two addresses to the bypass list. The first bypasses the proxy for all servers in the contoso.com domain; the second bypasses the proxy for all servers whose IP address begins with 192.168.
<configuration>
<system.net>
<defaultProxy>
<bypasslist>
<add address="[a-z]+\.contoso\.com$" />
<add address="192\.168\.\d{1,3}\.\d{1,3}" />
</bypasslist>
</defaultProxy>
</system.net>
</configuration>
