Disable browser cache in asp mvc

Here is a simple trick on how to disable browser cache in asp mvc application with an attribute.
If you have a base controller just add this to your base and all your request would have Pragma No-Cache

 public class NoCacheAttribute : ActionFilterAttribute
    {        
        public override void OnResultExecuting(ResultExecutingContext filterContext)
        {
            if (filterContext == null) throw new ArgumentNullException(“filterContext”);

            var cache = GetCache(filterContext);

            cache.SetExpires(DateTime.UtcNow.AddDays(-1));
            cache.SetValidUntilExpires(false);
            cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
            cache.SetCacheability(HttpCacheability.NoCache);
            cache.SetNoStore();

            base.OnResultExecuting(filterContext);
        }
       
        protected virtual HttpCachePolicyBase GetCache(ResultExecutingContext filterContext)
        {
            return filterContext.HttpContext.Response.Cache;
        }
     }
}

public class NoCacheAttribute : ActionFilterAttribute

{

public override void OnResultExecuting(ResultExecutingContext filterContext)

{

if (filterContext == null) throw new ArgumentNullException(“filterContext”);

var cache = GetCache(filterContext);

cache.SetExpires(DateTime.UtcNow.AddDays(–1));

cache.SetValidUntilExpires(false);

cache.SetRevalidation(HttpCacheRevalidation.AllCaches);

cache.SetCacheability(HttpCacheability.NoCache);

cache.SetNoStore();

base.OnResultExecuting(filterContext);

}

protected virtual HttpCachePolicyBase GetCache(ResultExecutingContext filterContext)

{

return filterContext.HttpContext.Response.Cache;

}

Simply add this to your base controller, and you are done 🙂
