-/**
- * The HttpSendSocket class extends the java.net.Socket class
- * by enclosing the data output stream in, then extracting the input
- * stream from, an HTTP protocol transmission.
- *
- * NOTES:
- *
- * Since the length of the output request must be known before the
- * HTTP header can be completed, all of the output is buffered by
- * an HttpOutputStream object until either an attempt is made to
- * read from this socket, or the socket is explicitly closed.
- *
- * On the first read attempt to read from this socket, the buffered
- * output is sent to the destination as the body of an HTTP POST
- * request.  All reads will then acquire data from the body of
- * the response.  A subsequent attempt to write to this socket will
- * throw an IOException.
