I have two CSS and configured to use Active-Backup stateful failover.
I also have several WWW and SSL servers.
I found that the client cannot get back to same server after failover.
I guess the problem is the stricky information is not replicate from master to backup.
Am I right ?
Is it help if I use exact match arrowpoint cookie ?
Thanks in advance.

HI,
if you do ASR (adaptive session redundancy) the stickiness is replicated as otherwise the statefull failover won't work (compare http://www.cisco.com/en/US/products/hw/contnetw/ps792/products_configuration_guide_chapter09186a0080157898.html#1065303)
there are issues mentioned in
http://www.cisco.com/en/US/products/hw/contnetw/ps792/products_field_notice09186a00801e061a.shtml
that ASR is not working because of a (fixed) BUG. Have a look at the workaround section and use the suggested images.
Regards,
Joerg

I opened a TAC case for this case. They said that the SSL session ID doesn't replicate to backup CSS.
