title: Getting IP address and port number from http.Client
body: <p>I'm making a http Client that keeps an open connection. I want to get the IP address of the client made. I know that I can give it its own ip address by using transport's Dial function. However is there a way that I can obtain its address after declaring the client?</p>
  <pre><code>var tr= &amp;http.Transport{DisableKeepAlives:false}
  var client = http.Client{Transport :tr}
  </code></pre>
