+/**
+ * The HttpReceiveSocket class extends the WrappedSocket class
+ * by removing the HTTP protocol packaging from the input stream and
+ * formatting the output stream as an HTTP response.
+ *
+ * NOTES:
+ *
+ * The output stream must be explicitly closed for the output to be
+ * sent, since the HttpResponseOutputStream needs to buffer the entire
+ * transmission to be able to fill in the content-length field of
+ * the HTTP header.  Closing this socket will do this.
+ *
+ * The constructor blocks until the HTTP protocol header
+ * is received.  This could be fixed, but I don't think it should be a
+ * problem because this object would not be created unless the
+ * HttpAwareServerSocket has detected the beginning of the header
+ * anyway, so the rest should be there.
+ *
+ * This socket can only be used to process one POST and reply to it.
+ * Another message would be received on a newly accepted socket anyway.
