HttpCacheVaryByHeaders.UserLanguage Property

 

Gets or sets a value indicating whether the ASP.NET output cache varies the cached responses by the Accept-Language header, and appends it to the out-going Vary HTTP header.

Namespace:   System.Web
Assembly:  System.Web (in System.Web.dll)

public bool UserLanguage { get; set; }

Property Value

Type: System.Boolean

true when ASP.NET output cache varies by the Accept-Language header and adds it to the Vary HTTP header sent to the client; otherwise, false. The default value is false.

The Vary header indicates the request-header fields that the server uses to determine which of multiple cached responses is sent in response to a client request. The Accept-Language field specifies that the server selects the response based on languages acceptable to the client.

For more information, see RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1, available on the World Wide Web Consortium (W3C) Web site. See section 14, "Header Field Definitions", for complete details.

The following code example demonstrates how some action is performed only if the UserLanguage property is true.

Response.Cache.VaryByHeaders.UserLanguage = true;
