// Any page that potentially contain sensitive information should not be cached
// on the user's browser and proxy servers. In ASP.NET MVC, you can use the
// OutputCache attribute to prevent caching for a controller action. For
// example:
[OutputCache(Location = OutputCacheLocation.None, NoStore = true)]
public ActionResult Index()
{
return View();
}
// This will result in the following headers:
//
// Cache-Control: no-cache, no-store
// Pragma: no-cache
// Expires: -1
//
// For ASP.NET Core MVC, use the ResponseCache attribute instead.
// ----------------------------------------------------------------------
[ResponseCache(Location = ResponseCacheLocation.None, NoStore = true)]
// Produces the following headers:
//
// Cache-Control: no-store,no-cache
// Pragma: no-cache
//
// The `OutputCache` attribute and the `ResponseCache` attribute can be applied
// both to actions (methods) as well as controllers (classes).
