You can use a centralized database to store session variables...the setting is found
on the "Variables" page in CF Administrator. I don't know much about hardware
clustering, but that's about your only solution if you're using a software-based
clustering approach...

That's great news! Do you know how you'd deal with server variables
in a
clustered environment, since they don't span across multiple
servers...?

I certainly hope client variables cant be more than 255 characters
my program has been lying to me <G>
At least in our Client repository we use the text data type
which allows for arbitrary data size. I have stored some pretty
huge stuff like a WDDX'd struct in the client cache, so I
think whatever the source it was slightly misinformed :))

Ok... does anyone have any information on client variables and the
preferred
methods of using them with a database backend.
Also, in the Mastering ColdFusion 4.5 book, it states that the maximum
length for a client variable is 255 chars. Is this limitation due to
the
varchar settings in the database or is it internal to ColdFusion. Or
could
you just increase the database to something like varchar(500) in SQL
Server
7.0
Any information is greatly appreciated.
Thanks,

Anyone have more information....
On page 193 of the "Developing Web Applications with ColdFusion 4.5"
manual
there's a couple sentences on Variable Caching.
"All client variable reads and writes are cached to help decrease the
overhead of client state management operations."
Does anyone have any details on exactly how the cache behaves for both
reads
and writes, timeouts, manipulating the cache, etc.
Thanks,
