Hi Thomas,
Thanks a lot. I am pretty sure that my question will be not answer in the
official cisco site. I have configured the stickness, it is working but in an
unpredictable manner - when server fails, connections (that have to be sticky)
are for some reason forwarded to the next server in the serverfarm.

This link might be helpful to you:

e_appliances/vA1_7_/configuration/slb/guide/classlb.html#wpxref39283
Basically, you configure two serverfarms, a primary and a backup. When all
servers in the primary are gone, you fail back to the sorry serverfarm, and it
looks like you can specify a different predictor (lb-algorithm) for each
serverfarm if you wish (ie leastconn & round-robin). I'm not sure that you
can make the primary sticky and not the backup.
HTH,

Hi experts,
If anyone has in depth experience with ACE please let me know. I am
facing a big problem with sticky serverfarm that need a fallback to
default round robin in case server becomes unavailable.
10x in advance,
Lora
