/**
 * The only time Yahoo can actually send us any packets is when we send it some. Yahoo encodes its packets in a POST
 * body - the format is the same binary representation used for direct connections (with one or two extra codes).
 * /*from w ww  .  ja  v a 2s  .  c om*/
 * After posting a packet, the connection will receive a HTTP response who's payload consists of four bytes followed
 * by zero or more packets. The first byte of the four is a count of packets encoded in the following body.
 * 
 * Each incoming packet is transfered to a queue, where receivePacket() takes them off - thus preserving the effect
 * that input and output packets are being received independently, as with other connection handlers. As
 * readPacket() can throw an exception, these are caught and transfered onto the queue too, then rethrown by
 * receivePacket() .
