title: Compress HTTP GET Response
body: <p>I am currently working on migrating few of my MVC3 Controllers to MVC4 Api Controllers.
  I have implemented Compression mechanism for MVC3 controller Get Method Responses by inherting <code>ActionFilterAttribute</code> and overriding <code>OnActionExecutiong</code> method. After some Research I found that I need to use <code>ActionFilterMethod</code> from <code>System.Web.HttpFilters</code>. It would be great if somebody can share piece of sample code to get me started for this compressing HTTP response using GZip</p>
