Disable browser cache for entire ASP.NET website

Question

I am looking for a method to disable the browser cache for an entire ASP.NET MVC Website

I found the following method:

Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
Response.Cache.SetNoStore();

And also a meta tag method (it won't work for me, since some MVC actions send partial HTML/JSON through Ajax, without a head, meta tag).

<meta http-equiv="PRAGMA" content="NO-CACHE">

But I am looking for a simple method to disable the browser cache for an entire website.

Create a class that inherits from IActionFilter.

public class NoCacheAttribute : ActionFilterAttribute
{  
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}

Then put attributes where needed...

[NoCache]
[HandleError]
public class AccountController : Controller
{
    [NoCache]
    [Authorize]
    public ActionResult ChangePassword()
    {
        return View();
    }
}
