Do you have a document how you did this? thx Maarten -----Oorspronkelijk bericht----- Van: Sharma, Siddharth [mailto:Siddharth.Sharma@Staples.com] Verzonden: maandag 31 juli 2006 23:06 Aan: Tomcat Users List Onderwerp: clustering problem Hi We have a 4 machine configuration. Each machine has: 1. 3 Tomcat instances (so total 12 instances) 2. 1 Apache with mod_jk (so total 4 Apaches) The Apaches/mod_jks are fronted by a hardware load balancer. Each mod_jk load balances across all 12 tomcats. In other words, you could hit any one of the four Apaches/mod_jks and get load balanced to any one of the 12 tomcats. Once you hit one tomcat, you are sticky to it. All this works, but I am wondering if there is a way to do tomcat instance targeting. In other words, indicate to mod_jk that the request should be sent to a specific tomcat instance. This is useful to check if each instance is up and accepting. I am not worried about DoS since a proxy sits between the client and the Apaches that maintains the jsessionid cookie for the client and does not accept it from the client. Any ideas?
