Live response problem

[ask4amit]

We are using the latest version of SupportSuit and live response .

The thing is, that we want to place it in a fail safe/ load balanced formation.
So we installed two instances of kayako with a shared database and a load balancer in front.

Now it works in the normal conditions, but with Live Response, this setup doesn't work. From what we could gather, the problem lies in SESSION sharing. Requests goes to the two servers in a round robin fashion. So if it works in the first request, in the next request it can't seem to find the session
and shows sessions expired error. So a chat keeps getting d/c. Messages being dropped etc etc.
The one message which we keep getting is

Unable to deliver the chat message. The chat session has either ended or expired

there have been few post regarding this issue

1. LiveSupport Chat Error message
2. An Error
3. Could not deliver chat message. Your chat session has either ended or expired

I couldn't find any concrete solution from either, most of them are old post and have ended abruptly. What i got was people needed to upgrade. I 'm using the latest version this should not be a problem.

So i have two questions basically.

1. How/where does kayako puts the session data ? database / file system ?
2. Is it possible to use live response in a load balanced setup? Is there a way to share the session data across the two servers?

it works perfectly if i shutdown one of the instances.

some one told me to upgrade to the CVS version. Well it has another problem, sumhow the damn upgrade option doesn't work. I have put it up in

supportsuit upgradation error

Now what i get from kayako people is just to create a support ticket. But they have got to realise that its not always possible to simply give the admin url / password to a 3rd party for any company. Moreover in most cases people try stuff in their local network before putting it up on the internet. Still i'm trying to arrange some thing in our staging setup, but then again the whole kayako is bounded to the domain name, so either the support people need to make entry in their hosts file or if you have to practically close our production site and redirect all traffic to our staging setup( through DNS) . So i think the whole support thing must be done LIVE and not as a ticket, or atleast they could agree on a particular time and for that short period either could be done. Still i think the kayako guys need to come up with something better to support their support than to simply ask for admin url, ssh , ftp access every time.

Just imagine if Microsoft starts asking for the access to your computer every time sommthing goes wrong
