title: Call WebApi controller from another controller
body: <p>So I have two projects in my solution. Both are WebApi. I have controllers in both and I can call them from the client side - javascript. 
  The problem is that I need to call a method in the controller of the second project from method in the controller of the first project. I also think I should state that the method I need to call is Post so I need to send it parameters as well.
  Is this possible at all? I heard about "RedirectToAction" method but I think this won't work in webapi.</p>
