Brad, (1) As far as JVM is concerned sockets in the TIME_WAIT state are considered closed. Those sockets are kept active for a while by the underlying OS in order to catch stray packets after the connection has been closed by the JVM process. You need to tweak TCP/IP settings of the OS you are using if you want to reduce the period of time sockets are kept in the TIME_WAIT state. > If that's the case, then fair enough but I was hoping there would be > some way to make commons-http re-use a socket.
