Paul,
You can set up client management from the cfapplication tag and in the cf
server administrator you can create a db to hold client vars. All servers
in the cluster need to know about the DB.
Create the WDDX packet as a client variable.
Now when you need to save state, put the data into a WDDX packet. When you
need to get the data again, deserialize the packet.
Mike.

Subject: Re: Session vars in a clustered environment
WDDX is an alternative to "Sticky Sessions"
The idea is to pass a WDDX packet back and
and forth in each page request. This allows
pages displayed to a given user to be from
different web servers. Perhaps we can call
this "non-Sticky Sessions" for short, or,
"Sessions_That_Aren't_Sticky_But_They_Maintain_State_Anyway"
This probably requires JS to enable each
link/page request to act as a form submit
and pass the WDDX packet as a hidden variable
back to the server. I'd be interested if
anyone comes up with an alternative.
best, paul

With
