Question

I’m familiar with using a HttpModule to time requests but those don’t really hook into ASP.NET MVC’s view system. Can this be done by starting a timer somewhere in global.asax and then accessing it in _layout.cshtml?

Answer 1

1) You can check the start time and end time of a request in Begin_Request and End_Request events of application class
2) You can define a custom HttpModule
3)You can define a custom attribute as follows:

public class RequestTimerAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        //Mark the Start Time 
                MarkTime("Start");
    }

    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
        //Mark the Start Time 
                MarkTime("End");
    }

    void MarkTime(string EventName)
    {
        //Handle the logic here to log the time 
    }        
}
