title: When running selenium with capybara/rails, how do I configure the server?
body: <p>Normally I use the rails dev server at port 3000.</p>
  
  <p>Capybara/Cucumber uses <code>Capybara.server_port = 31337</code>. If I swap from the default driver to selenium, it looks like it tries to connect on port 80.</p>
  
  <p>I'm trying to understand:</p>
  
  <ul>
  <li>When using selenium, do I need to separately instantiate a test server on the test environment.</li>
  <li>If the answer to the above question is yes, how can I make it so I can seamlessly swap between web drivers without having to keep changing things?</li>
  </ul>
  
  <p>If someone has an example of a env.rb configuration that would help please let me know!</p>
  
  <p>Thanks!</p>
  
  <p>Chris.</p>
