title: How to allow web requests when using VCR / WebMock?
body: <p>I'm currently using RSpec2, Cucumber and VCR (via WebMock), and everything's working great. </p>
  
  <p>With VCR normally all requests are recorded and then replayed against the recorded cassettes.</p>
  
  <p>Now I want to allow real web requests in some scenarios:</p>
  
  <ul>
  <li>In Cucumber, I've setup a "live" profile which runs any test tagged with <code>@live</code>. For these tests – and these tests only – I'd like to allow real web requests.</li>
  <li>I want from time to time run the tests against the real api and ignore the recordings</li>
  </ul>
