title: Angular 4 routing not works when invoke direct url path
body: <p>I have an angular 4 apps with many routes. 
  My issue is really simple to understand. All routing works fine inside the app.
  The problem come out when I go directly to a specific url
  Ex. 
   Base url app is <a href="http://myserver/" rel="nofollow noreferrer">http://myserver/</a>
  and when I invoke the url above I see my home page (<a href="http://myserver/home" rel="nofollow noreferrer">http://myserver/home</a>)
  if I invoke a url of a specific path (ex. <a href="http://myserver/anotherpathpage" rel="nofollow noreferrer">http://myserver/anotherpathpage</a>) the app redirects me always on the home.</p>
  
  <p>Any idea? 
  I'm using html5 location strategy (no hash in the url) and my base href is "/"</p>
  
  <p>Thanks a lot
