The caveat with that solution is that now you are doing TCP session load balancing, not HTTP load balancing. When the traffic flows in SSL through the LB, it prevents the LB to make load balancing decisions based on the HTTP protocol. And to do stickyness with TCP load balancing, you don't have much information except the SRC and DEST IP addresses to go by.(and the session itself, which is not relevant when it comes to HTTP since it is stateless) Filip - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Load Balancing Tomcat 5.0.X, hardware or software?
My vote goes to appliance, but Filip is completely correct, this is a budget based decision. The higher up in your architecture you deal with SSL the better in my experience. (especially in stateless farms) I would look into L2 caching (like EHCache + Hibernate or Terracotta) if you decide to build a LB yourself. Good luck Dwayne On 8/31/07, Filip Hanik - Dev Lists [EMAIL PROTECTED] wrote: bajistaman wrote: And what about SSL?, it sure makes life easier to have the LB take care of it, and if you look at it from a signed certificate licensing standpoint, cheaper. verisign and the other dudes, like to charge for per-box you wish to install the cert on. it is better to let the load balancer to take care of it or every node in the farm?

Load Balancing Tomcat 5.0.X, hardware or software?
Hi!, I'm trying to create a stateless tomcat's farm but wanted sticky session mechanism. What is the best way to achieve this?, using hardware or software load balancing?

Re: Load Balancing Tomcat 5.0.X, hardware or software?
whether you run software on your own machines, or buy an appliance with loadbalancing software (what you refer to hardware loadbalancer) is dependent on your budget, nothing else :) Filip bajistaman wrote: Hi!, I'm trying to create a stateless tomcat's farm but wanted sticky session mechanism.
