title: Username and password appearing in the URL
body: <p>In my rails app, I have a login page like this:</p>
  
  <pre><code>&lt;body&gt;  
      &lt;form action="/my_app/homepage" method="get" class="navbar-form pull-left"&gt;
      &lt;input name="username" type="text" class="span2"&gt;
       &lt;input name="password" type="password" class="span2"&gt;
      &lt;button type="submit" class="btn"&gt;Submit&lt;/button&gt;
      &lt;/form&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>When I click on the <code>Submit</code> button it takes me to the <code>/my_app/homepage</code> but at the same time it also displays the username and password in the addressbar.</p>
  
  <p>Am I doing it the wrong way? How can I avoid displaying the username &amp; password?</p>
