// Examine the response status text
NSLog(@"%@%@",@"response status text: ",http.LastStatusText);

// Examine the full response header.
NSLog(@"%@",@"response header:");

// Examine the response content-type

NSLog(@"%@",@"----");

// Get a header field value by name:
NSLog(@"%@%@",@"ETag: ",[mime GetHeaderField: @"ETag"]);
