title: Determining what requests happen after UI interaction with Rails, Capybara
body: <p>I'm using Capybara for web crawling, and I have the following challenge: after I interact with some DOM elements (e.g. click a button), I want to know (or make a good guess) if a new page is loading and if any AJAX requests are taking place.  Because I'm crawling sites I don't necessarily control, I don't have access to the server-side state or know what to expect (i.e. it's not a matter of waiting for the page to load, it's a matter of knowing if it's happening at all).</p>
  
  <p>The best case scenario would be if I could query a list of recent/ongoing/completed HTTP requests and get data from them.  </p>
  
  <p>Alternatively it would be nice if I could at least find out if the page is reloading/has reloaded since my last interaction.</p>
  
  <p>At the very least I could check to see if the URL of the page I'm on matches the URL I used to be on, but this misses the AJAX requests, page refreshes, and doesn't wait for the page load to happen.  Looking for something better than this.</p>
  
  <p>I'm looking for something that works with selenium.  For the non-AJAX case I would like it to work with webkit too.  Any suggestions?</p>
