Element	Description
add	Optional element. Adds an alias for a specific user agent to an internal collection of user agent aliases.
clear	Optional element. Removes all aliases that are currently contained in or inherited from the specified Web.config file.
remove	Optional element. Removes an alias for a specific user agent from an internal collection of user agent aliases. The value must exactly match that of a previous add directive. Wildcard selections are not supported.

Element	Description
configuration	Specifies the required root element in every configuration file that is used by the common language runtime and the .NET Framework applications.
system.web	Specifies the root element for the ASP.NET configuration section.

The collection of user agent aliases indicates the target user agents that ASP.NET server controls should render content for.

The following default clientTarget element is configured in the root Web.config file in the .NET Framework version 2.0.

<clientTarget>
   <add alias = "ie5" userAgent = "Mozilla/4.0 ( compatible; MSIE 5.5; Windows NT 4.0" />
   <add alias = "ie4" userAgent = "Mozilla/4.0 ( compatible; MSIE 4.0; Windows NT 4.0" />
   <add alias = "uplevel" userAgent = "Mozilla/4.0 ( compatible; MSIE 5.5; Windows NT 5.1 )" />
   <add alias = "downlevel" userAgent = "Generic Downlevel" />
</clientTarget>

The following default clientTarget element is configured in the Machine.config file in the .NET Framework versions 1.0 and 1.1.

<clientTarget>
   <add alias = "ie5" userAgent = "Mozilla/4.0 ( compatible; MSIE 5.5; Windows NT 4.0 )" />
   <add alias = "ie4" userAgent = "Mozilla/4.0 ( compatible; MSIE 4.0; Windows NT 4.0 )" />
   <add alias = "uplevel" userAgent = "Mozilla/4.0 ( compatible; MSIE 4.0; Windows NT 4.0 )" />
   <add alias = "downlevel" userAgent = "Unknown" />
</clientTarget>

The following code example demonstrates how to add four user agent aliases.

<configuration>
   <system.web>
      <clientTarget>
         <add alias = "ie5" userAgent = "Mozilla/4.0 ( compatible;MSIE 5.5;Windows NT 4.0 )" />
         <add alias = "ie4" userAgent = "Mozilla/4.0 ( compatible;MSIE 4.0;Windows NT 4.0 )" />
         <add alias = "uplevel" userAgent = "Mozilla/4.0 ( compatible;MSIE 4.0;Windows NT 4.0 )" />
         <add alias = "downlevel" userAgent = "Unknown" />
      </clientTarget>
   </system.web>
</configuration>
