title: in rails, What is the value returned in for a checkbox?
body: <p>I want to set a cookie to expire in 1 year if the 'remember me' checkbox is checked.</p>
  
  <p>I have a checkbox form input like:</p>
  
  <pre><code>&lt;%= check_box_tag 'remember', '', false, :class =&gt; 'checkbox' %&gt;
  </code></pre>
  
  <p>What will the value be when it gets posted?</p>
  
  <p>Will it be true/false or checked or 1 or? I set the value to '' in the helper.</p>
