Agreed on not having to recode session to client. But I will say getting fail over to
work with Cluster Cats was a pain in the butt last time we did it! So allow at least a
week if this is your
first time doing this... ;-) (The second time it may only take 2 hours)

<br>>
<br>>
<br>> Hi,
<br>>
<br>> I had developed a coldfusion app using session variables.
<br>> Just worry, is the session variable work as normal in Load Balancing
?
<br>> For example, i have 2 servers here. i have a load balancer for these
2
<br>> servers to manage the web access traffic.
<br>> If i now login into the server 1, during the half way working, will
the
<br>load
<br>> balancer auto switch me to the server 2; if there is a high traffic
? or i
<br>> may still remain in server 1 ?
<br>> pls advice...
<br>>
<br>> thx...
<br>>
<br>> regards,
<br>> Han
