Stevens' "TCP/IP Illustrated, Volume 1" has the TCP state transition diagram. It is p. 241 in my edition. For a SOAP client, the app leaves the ESTABLISHED state by requesting a close(), which causes TCP/IP to send a FIN to the server. There are a couple of ways TCP/IP can then move to the TIME_WAIT state, but it will always pass through that state. It will stay in that state for 2 * MSL. MSL is specified in RFC 793 as 2 minutes, but as Stevens notes, some implementations use a different value.

My question is: when are the socket connections released? Do I have to do anything explicitly to close it? Server ends says the socket is going into TIME_WAIT state (sometimes?). Will this happen if client timesout before response is received? I am on jdk1.3. Thanks for any help!
