HttpCacheVaryByHeaders.UserLanguage Property

Definition

Namespace:

System.Web

Assembly:

System.Web.dll

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.

public:
 property bool UserLanguage { bool get(); void set(bool value); };

public bool UserLanguage { get; set; }

member this.UserLanguage : bool with get, set

Public Property UserLanguage As Boolean

Property Value

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.

Examples

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

Response.Cache.VaryByHeaders.UserLanguage = true;

Response.Cache.VaryByHeaders.UserLanguage = True

Remarks

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.
