If you're using ASP.net MVC, consider adding an extension method to easily implement no caching like so:

    public static void NoCache(this HttpResponse Response)
    {
        Response.Cache.SetNoStore();
        Response.Cache.SetExpires(DateTime.MinValue);
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetValidUntilExpires(false);

        Response.Expires = -1;
        Response.ExpiresAbsolute = DateTime.MinValue;
        Response.AddHeader("Cache-Control", "no-cache");
        Response.AddHeader("Pragma", "no-cache");
    }
