title: duplicate request by NSURLconnection
body: <p>am using NSURLConnection to connect a server at the port 443 for authentication. Only for BAD credentials, its making two requests, even though i made only one request. I debugged by logging server &amp; simulator/device using sniffer.</p>
  
  <p>But i am making a  call only one time &amp; getting only one response. i debugged it using NSLog in simulator/iphone/ipad</p>
