FYI - the work to make your sessions sticky will be on your Linux box, not
on CF.

Subject: Re: CF 9 Standard Load Bal Sticky Sessions
I am trying to setup a failover environment for my web application. We are
using CF9 standard and LVS (Linux Virtual Server) as the load
balancer (LB). My web application uses session variables to remember form
values posted in a process (eg would work like a session web
shopping cart). The issue is the session values are lost when the LB
processes the request as it flips between the different servers between
each request.
Is it possible to setup sticky sessions so that the session variables are
retained across the web session? I'm concerned the only way to do this
is to update the application to client variables and store in the database
etc. Any thoughts or recommendations appreciated.
Yes, you can use sticky sessions with CF Standard. Of course, if one
server fails, the sessions on that server will be lost. If you need
session failover with CF Standard, you'll have to use client
variables in a database or some analogous thing you build yourself.
