WebTCP ZeroWindow. Set when the receive window size is zero and none of SYN, FIN, or RST are set. The window field in each TCP header advertises the amount of data a receiver can accept. If the receiver can’t accept any more data it will set the window value to zero, which tells the sender to pause its transmission. WebSYN starts a connection; you'll usually only see it when the connection's being established. But all data being sent via TCP requires an ACK.
