title: Model binding on POST with query string AND form parameters
body: <p>What is the defined behavior for form binding in ASP.NET/MVC if you POST a form and its <strong>action</strong> has query parameters <strong>and</strong> you have form data?</p>
  
  <p>For example:</p>
  
  <pre><code>&lt;form action="my/action?foo=1" method="post"&gt;
       &lt;input type="hidden" name="bar" value="2"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>If such a form is submitted should the controller get both <code>foo</code> and <code>bar</code> or only one of them?</p>
