title: NSURLConnection "lost network connection" error?
body: <p>I am developing an app that will upload the image from the iphone to a server. In server side there is a php program to handle the uploaded image. I am using the NSURLConnection with the Post method and have set the post body of the request. When I upload the image, I could see the image uploaded 3 times(in the server), but after sometime didFailWithError: is called stating that "lost network connection". What could be the reason for this? My doubt is that why is that image is uploaded multiple times?  I have set the timeout of the request to 3600.0</p>
  
  <p>Any help is appreciated.</p>
  
  <p>Thanks</p>
