HttpCachePolicy::SetAllowResponseInBrowserHistory Method
Makes the response is available in the client browser History cache, regardless of the HttpCacheability setting made on the server, when the allow parameter is true.
Assembly: System.Web (in System.Web.dll)
Parameters
- allow
- Type: System::Boolean
true to direct the client browser to store responses in the History folder; otherwise false. The default is false.
When HttpCacheability is set to NoCache or ServerAndNoCache the Expires HTTP header is by default set to -1; this tells the client not to cache responses in the History folder, so that when you use the back/forward buttons the client requests a new version of the response each time. You can override this behavior by calling the SetAllowResponseInBrowserHistory method with the allow parameter set to true.
If HttpCacheability is set to values other than NoCache or ServerAndNoCache, calling the SetAllowResponseInBrowserHistory method with either value for allow has no effect.
SetAllowResponseInBrowserHistory is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
The following code example demonstrates how to override the SetAllowResponseInBrowserHistory method to direct the client to store the responses in its history in a custom HttpCachePolicy.
