Multiple OutputCache in MVC

Can we have multiple OutputCache defined for an action? For ex. say I want to store OutputCache copy one in Server and another one in Client. I know that this we can do with Location=OutputCacheLocation.ServerAndClient but say I want to specify different Duration for Client and Server, having a bigger Duration for Server and smaller Duration for Client? So with this requirement can I have it as below?

[OutputCache(Duration = 3600, Location = OutputCacheLocation.Server, VaryByParam = "pID", NoStore = true)] //Server Cache for 1 hour
[OutputCache(Duration = 600, Location = OutputCacheLocation.Client, VaryByParam = "pID", NoStore = true)] //Client Cache for 10 minutes
public ActionResult GetDetails(string pID)
{
    //some code
    return View(model);
}

Will this be valid to have or MVC takes latest OutputCache into consideration?

If you look at the source of OutputCacheAttribute you will notice that the attribute is defined with AllowMultiple property set to false:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
public class OutputCacheAttribute : ActionFilterAttribute, IExceptionFilter

So it won't work
