Sticky Sessions

[George Christman]

Hi guys, so I've had a slew of strange behaviors over the past few months
with a few different Tapestry components such as Tapestry Grid, Tapestry
Captcha, and writting/removing cookies. Last night I was finally able to
fix them, but at the cost of a sticky session. My application sits behind a
load balancer, so my question is why do I need to use a sticky session and
how do I avoid the use of them? I'm concerned with the fact this is going
to cause a scaling dilemma.
