I've got a few questions regarding the functionality of mod-cluster:
*#1 Does mod-cluster support domains with sticky sessions ?_
_*I recall discussing this on *this* mailing list, and IIRC Paul
confirmed that mod-cluster supports domains with sticky sessions. I
actually tried this out and t worked.
I just need a quick confirmation on this. For config details, I'll go
and re-read the archives.
*#2 Disabling an entire domain*
I want to disable not just 1 node in a domain, but all nodes in a given
domain. Is this possible ? If so, I'd assume this is done through
*#2a: How do I know when all sessions of all nodes of a given domain
have expired ?*
This is necessary to know when I can shut down all nodes of a given domain
*#3 Starting an entire domain in disabled mode*
I want to start all nodes, one by one, in a given domain as *disabled*
(all webapps). Is it sufficient to just start all nodes as disabled ? Is
it possible to start a node in disabled mode at all ?
*#4 Enabling an entire domain*
When all nodes in a domain have been started as disabled (step #3), I'd
like to tell the httpds to enable all (or a selected set of) webapps in
a given domain, in all nodes of that domain. Is this possible ?
The point behind these 4 questions is that I want to demo how to disable
a domain, shut it down, upgrade the HW/SW, start it again, and re-enable it.
