發行項

Specifies the HTTP request string that are used to parse the browser capability information that is stored in the filter and case elements.

Note
Using the browserCaps element in the Web.config file to define browsers is deprecated in the .NET Framework 2.0 but is still supported. The data in this element is merged with the information from the browser definition files (.browser) that are located in the machine-level %SystemRoot%\Microsoft.NET\Framework\version\CONFIG\Browsers folder and any existing application-level App_Browsers folders. For more information, see Browser Definition File Schema (browsers Element).

Remarks

The use element specifies the HTTP request string that is used to parse the browser capability information that is stored in the filter and case elements.

Default Configuration

In the .NET Framework version 2.0, the use element is not configured because the browserCaps element is deprecated in favor of using browser definition files to specify supported browsers and the capabilities for the browsers. For more information, see Browser Definition File Schema (browsers Element).

In the .NET Framework versions 1.0 and 1.1, the default use elements that are configured in the Machine.config file are too numerous to list here. For updates to the browser data, go to cyScape, Inc. at http://www.cyscape.com/browsercaps. Periodic device updates replace this browser capabilities section.

Example

The following code example demonstrates how to specify that the IIS HTTP_USER_AGENT server variable is the source of the browser capabilities information.

<use var="HTTP_USER_AGENT">
