You may want to disable browser caching for all pages rendered by controllers  i e  HTML pages   but keep caching in place for resources such as scripts  style sheets  and images  If you re using MVC4  bundling and minification  you ll want to keep the default cache durations for scripts and stylesheets  very long durations  since the cache gets invalidated based on a change to a unique URL  not based on time    In MVC4   to disable browser caching across all controllers  but retain it for anything not served by a controller  add this to FilterConfig RegisterGlobalFilters   filters Add new DisableCache       Define DisableCache as follows   class DisableCache   ActionFilterAttribute       public override void OnResultExecuting ResultExecutingContext filterContext                filterContext HttpContext Response Cache SetCacheability HttpCacheability NoCache

Instead of rolling your own  simply use what s provided for you   As mentioned previously  do not disable caching for everything  For instance  jQuery scripts used heavily in ASP NET MVC should be cached  Actually ideally you should be using a CDN for those anyway  but my point is some content should be cached   What I find works best here rather than sprinkling the  OutputCache  everywhere is to use a class    System Web Mvc OutputCache NoStore   true  Duration   0  VaryByParam         public class NoCacheController    Controller       All of your controllers you want to disable caching for then inherit from this controller   If you need to override the defaults in the NoCacheController class  simply specify the cache settings on your action method and the settings on your Action method will take precedence    HttpGet   OutputCache NoStore   true  Duration   60  VaryByParam         public ViewResult Index

I implemented all the previous answers and still had one view that did not work correctly   It turned out the name of the view I was having the problem with was named  Recent   Apparently this confused the Internet nbsp Explorer browser   After I changed the view name  in the controller  to a different name  I chose to  Recent5    the solutions above started to work
