title: How to get the incoming cookies to a Mule HTTP end point
body: <p>I'm using Mule EE 3.5.2.
  I'm posting an HTTP request (PostMan) with a cookie header, to an incoming HTTP end point in Mule. How can I read this Cookie?
  In practice this cookie will be coming through an NGinX proxy; i need it to pass to another application.</p>
