some one said this a long time ago.
 
"Some problems are solved with hardware best."
 
this is most likely a case.  there are commercial packages out there capable of doing cookie
based load balancing. Resonate comes to mind. It's expensive, but it does work. Talk to their
sales reps and they'll glad talk about their big customers.

I would not use *any* software load balancer in production under load.
AOL has a problem, the incoming IP can change between requests as AOL users get routed through
different gateways. There are two
ways around this:

1. Force AOL users into HTTPS, that way their gateway stays the same
2. Use a load balancer (hardware, preferred) that sets a cookie to keep track of the route.

Do you happen to know if Pen deals with AOL clients? (I'm looking for a load balancer at the
moment that needs to preserve session
data and deal with a large number of AOL clients)
