- /**
- * This class allows TCP socket connections through HTTP proxies in accordance with
- * RFC 2817:
- *
- * ftp://ftp.rfc-editor.org/in-notes/rfc2817.txt
- *
- * It can also be used to make direct connections to a destination, as well. If you
- * pass the host and port into the constructor, no proxy will be used. You can also
- * call connect, passing in the host and the port, and if you didn't set the proxy
- * info, a direct connection will be made. A proxy is only used after you have called
- * the setProxyInfo function.
- *
- * The connection to and negotiation with the proxy is completely hidden. All the
- * same events are thrown whether you are using a proxy or not, and the data you
- * receive from the target server will look exact as it would if you were connected
- * to it directly rather than through a proxy.
