                    ex.printStackTrace()
                }
            }

}

That syntax is freaking me out. It looks so much like Java… but the semicolons are missing!

Also, you might want to use \r\n in the future. HTTP seems to allow \n in media (RFC 2616, 3.7.1 Canonicalization and Text Defaults, second paragraph), but if you use it in the headers, you’re probably just lucky if the user agent accepts it.
