title: Slim3 redirect GET request as POST request
body: <p>Just started learning <code>Slim3</code>. Have been spending some time figuring out how to perform redirects with overriding original request type with no success. </p>
  
  <p>I want the <code>/origin</code> route to perform the redirect to <code>/dest</code> route. 
  <code>/origin</code> route receives <code>GET</code> request performs validation and after success redirects with <code>POST</code> request to <code>/dest</code> uri route. Here is the screenshot. I think I am doing something dumb here:</p>
  
  <pre><code>$app-&gt;get('/origin', function($req,$res,$args)
  {
      $req= $req-&gt;withHeader('X-Http-Method-Override','POST');
      return $res-&gt;withRedirect('/dest');
  });
  
  $app-&gt;post('/dest', function($req,$res,$args)
  {
      echo "this is destination page";
  });
  </code></pre>
