title: What does NSURLConnection's error code "-1009" mean?
body: <p>When I send a request and get an error with the error code <code>-1009</code>, what does that mean? I'm not sure how to handle it.</p>
  
  <pre><code>- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
        NSLog(@"connection didFailWithError");
  
     if(error.code==-1009){       
        //do something           
     }    
  }
  </code></pre>
