I have apache 2.0.43, Tomcat 4.1.24/Jboss 3.2.1 and using both mod_jk 1.2.5 and 2.02 (mod_jk/2 = seems to work the same on both 1.2 and 2.0).
-There is no tomcat on the apache server. -I have 2 or more tomcat servers. -Load balancing is working OK (as good as it mod_jk/2 balances). - Tomcat is not clustered Problem is when a worker leaves the network. If the worker is the first one in the list things are much worse (especially for session less requests). The mod_jk/2 tries a TCP connection to the first worker. It appears to try several times 8, 10, not sure. We must wait for this TCP connection to time-out before making a connection to the next worker. It appears to mark the server in "failed" mode for 10 - 15 seconds. The next request that comes in after that delay, mod_jk/2 tries to make the send the request to the dead worker and the TCP connection must again time-out before the worker is disabled for another 10 - 15 seconds. Q. - Is there a way to have mod_jk/2 keep the worker flagged as failed until some sort of app-app message is successful? - keep trying the TCP connection and keep the worker in flagged as failed until the server responds to the TCP request (accepted or rejected)? - Is there some well known method to deal with a server that drops from the network without manually removing the worker from the properties file? - Is there a way to change the length of time a server is considered dead before sending a new connection to it? - Another connector between Apache and Tomcat to use that does not exhibit this behavior? I have tried a large number of configuration changes for both mod_jk 1.2.x and 2.x as well as different mod_jk versions.

Hi, Does Tomcat 5 allow starting, stopping and/or restarting of a context without affecting the other contexts of the same webapp? Also, can a context be stopped or restarted gracefully(ie keep running until all of the sessions are dead)?
