title: Where and how to use interceptors in web application?
body: <p>I am interested in interceptor concept in recent times. I know that this concept is used in many libraries like NHibernate, Entity Framework and others. But i am interested in how to use this concept in ASP.NET MVC web application. </p>
  
  <p>Where it is usefull to use it in Mvc Web application? </p>
  
  <p>Is there any open source Asp.Net Mvc project which use interceptors ?</p>
  
  <p>Asp.net Mvc already support a kind of interceptor for controller with filters. It is better to use filters instead of interceptors ? </p>
