title: Webdriver - which proxy to use to log all requests urls
body: <p>I use Firefox driver. I'd want to proxy traffic and log urls of all requests that pass through proxy.</p>
  
  <p>The requirements for proxy are:</p>
  
  <ul>
  <li>It shouldn't modify traffic</li>
  <li>I should be able to modify location where log is saved programmatically</li>
  <li>I should be able to clear log at any moment</li>
  <li>Log shouldn't be shared across multiple Webdriver threads</li>
  </ul>
  
  <p>I thought about Browsermob proxy but HAR seems to be too heavy solution for logging just request urls. Also I don't know if Browsermob proxy's HAR is able to handle tens of thousands of entries.</p>
