title: MVC Error handling using Action Filters
body: <p>I would like to know best practice to handle exceptions.</p>
  
  <p>I have 3 types of exception flows</p>
  
  <p>1)  Warnings: - In this I am required to display the partial data received from the service and also the error code/ message.
  2)  Business errors: - In this no data just the error code is received but I want to display the view with all the controls (e.g. dropdown) and the error message. 
  3)  System failure errors: - In this scenario I would like to redirect to custom error page.</p>
  
  <p>I am using Using ASP.NET MVC and lang is C#</p>
