title: OWIN self static file server multiple routes
body: <p>I have configured in my Owin a webApi and an static file server to fetch some files that we will need in my app.</p>
  
  <pre><code>public void Configuration(IAppBuilder application)
  {
     //Other middlewares and configurations
      ....
     application.UseFileServer(new FileServerOptions()
     {
         RequestPath = new PathString("/myPath1/public"),
         FileSystem = new PhysicalFileSystem(m_FolderPathProvider.myPath1FolderPublic)
     });
  
         // Attribute routing.
              .....
   }
  </code></pre>
  
  <p>This is working like a charm. What a I need it's to declare another FileServer for another path and another different physical folder. What I'm frightening is if I do it in the same way I will override this one and I will have only one. So how can I declare a second fileserver?</p>
  
  <p>Thank you.</p>
