property bool UserLanguage { bool get(); void set(bool value); };public bool UserLanguage { get; set; }member this.UserLanguage : bool with get, setPublic Property UserLanguage As BooleanProperty Value
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.
