Forwarding http requests to a node or not is not directly related to pind_mode. Requests are forwarded to nodes, that are not in error state as long as session stickyness allows to use the node. If by request you mean a CPing, then: by default all pings are disabled. You can enable using either ping_mode or (for compatibility reasons) the old style connect_timeout and prepost_timeout. >From the point of view of mod_jk a node is not down, but either in error state or not. If it is in error state no communication is sent, but after a minute it is put in probe mode, which means it will get a single rquest to find out, whether it is again ok or not. In the latter case it is put in error mode again. > 2. Does socket_timeout mean how long the socket connection will be > kept open? So it actually is like a session timeout? socket_timeout is a difficult beast and I generally do not recommend using it. mod_jk uses it in some special situations in order to be able to abort waiting for data. It is not directly "how long a socket will e kept open". How long a socket is kept open depends on how the swocket gets used. Usually you can get away pretty good using CPing and ping_timeout, socket_connect_timeout, eventually reply_timeout with max_reply_timeouts. > 3.

Stopping the worker in the sense of setting activation to stop is *the* right way of telling mod_jk to not sending any more requests to the worker. If you only want to disable starting new sessions you use activation set to disable.
