I replied to your direct message but important for the list. The hot standby feature was added in 2.2.4 development, my bad, its already in the docs too. I've never used it so I'm not quite sure how you would do the hot stand by on 2.2.3 or older with the mod_proxy load balancer. You can use mod_jk which does provide those features.
I stopped using mod_jk because it doesn't work properly with my firewall that segregates my segments. One dropped connection a boom mod_jk gets confused. -----Original Message----- From: Anil Ranka [mailto:[EMAIL PROTECTED] Sent: Thursday, September 28, 2006 3:56 PM To: Tomcat Users List Subject: Re: Help with Tomcat Clustering and load balancing Chris, I am using Apache 2.2.3 on Windows XP.
