JSP Load balancing with LVS?

2000-03-16 Thread Jim Huang 

Hello Friends,

Anyone knows a way to distribute load to webservers running JSP?
I am setting up LVS ( linux virtual server) to balance load on my
webservers.
It works fine for static html pages but how do I distribute JSP(tomcat)
load?
Should I run multiple tomcat? If so how do I maintain user sessions?


Thanks for any input.

How to distribute tomcat load to multiple servers?

2000-03-24 Thread Jim Huang 

Hi JSP interest list,
Anyone knows how to distribute tomcat load to multiple servers? If
this is impossible, how does JSP handle salability?




Thanks for any input.
