title: Calling controller's action from another controller in expressjs
body: <p>In my expressjs / sailsjs app, I have 2 controllers:</p>
  
  <pre><code>- MainController only used to display the pages (for instance /signin route displays the signin page)
  - ProxyController that handles several action (API calls)
  </code></pre>
  
  <p>In one action of ProxyController I need to redirect to the signin page, I use the res.redirect('/signin') but nothing happens.</p>
  
  <p>In the routes I have:</p>
  
  <pre><code>    '/signin' : {
         controller: 'main',
         action: 'signin'
      },
  </code></pre>
  
  <p>Any idea on how can I call the MainController's signin action from ProxyController ?</p>
