Local Director supports SSL3 sticky sessions so if you're just using SSL3 LD
will send requests with SSL sessions back to the original server that the
load balancer picked. It doesn't handle SSL2 at all in this configuration
though and you'll end up seeing error pages in the browser.
If you do need SSL2 you could try using client IP based sticky sessions.
This may cause load imbalances though.

I'm not sure which model of Cisco gear you're using. Some Cisco models
allow different load balancing methods. Whereas with round robin, if
you're unlucky, you can experience occasional problems, you should be
able
to select load balancing based on utilization. Even lower end
Acedirector (Alteon, Nortel) can do that, so your Cisco might be able to
do
that too. If not, ask about an upgrade, as switching to Alteon would
cost you over $10k.
