Hi Mark the delta is socket_timeout is a universal timeout for the connection more specifically Socket timeout in seconds used for communication channel between JK and remote host. If remote host does not respond inside that timeout the JK will generate an error, and retry again. If set to value zero (default) the JK will wait for infinite on all socket operations. What to do if the tomcat connection_timeout is set lower than the socket timeout from AJP?
on the other hand reply-timeout gets replies from tomcat via ajp13/ajp14 there are 3 conditions which would cause the reply from tomcat to abort (recovery_options are set in workers.properties) 1)tomcat is down or experienced network problems marked unrecoverable if recovery_options has RECOVER_ABORT_IF_TCGETREQUEST (recovery_options=1) or RECOVER_ABORT_IF_TCSENDHEADER (recovery_options=2) set 2)tomcat is down or refuses connection marked unrecoverable if recovery_options has RECOVER_ABORT_IF_TCGETREQUEST (recovery_options=1) set 3)tomcat is down or experienced network problem in which case a partial response has been sent back to client marked unrecoverable if RECOVER_ABORT_IF_TCSENDHEADER (recovery_options=2) is set --------------------------------------------------------------------------- This e-mail message (including attachments, if any) is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, proprietary , confidential and exempt from disclosure.
