Our websites are loadbalanced thru our ACE modules and we are using the sticky feature.
Sticky is needed so that the customers session will retain the content of its shopping basket.
About 10% of our customers complain that the basket is emptied during a session, forcing them to start over. In our logs we indeed see that some users are balanced to another server during a session. Apparently in these cases the sticky feature is ignored somehow.
My question is, what are the possible triggers that the ACE uses to dismiss the sticky for a given session and start a new one?
Could it for example be caused by an html-page containing a link to another vip than the vip the page is originally served from?
Or could a simple spelling-error in a link be the trigger?
Looking forward to any answer.
