title: How do I know if I need "WCF HTTP Activation" in my application?
body: <p>I have an MVC3 ASP.NET application. If I iterate over the list of loaded <code>IHttpModule</code>s I see that there's <code>ServiceModel</code> listed which is a module for <a href="https://stackoverflow.com/a/3015160/57428">Windows Communication Foundation HTTP Activation</a>.</p>
  
  <p>I suspect I don't need this module and consider having this module removed.</p>
  
  <p>How do I know if I really need it?</p>
