Cool Here You Go (this the serialize and deserialize functions....they only work if you adhere to a naming conventions like that illustrated in the attached code files...but feel free to seek inspiration from them and improve upon them). They are pretty loose and I just threw in some comments for you to know what the heck is going on. You can just pop in the files into a single directory in your wwwroot, and call the test.cfm page. Also, you could cut and paste the serialize/deserialize functions and put them into your CFusionMX/wwwroot/web-inf/cftags/component.cfc file so that all the cfcs have access to them? Not a recommended, but will work for a quick test.
Hope this helps....sorry it is so sloppy, just haven't had time to clean it
up.

Justin,
Right now, I'm simply serializing/deserializing some nested structs and
arrays and using cfcs to manipulate them. This is for an app that is
1) Going to be deployed across a cluster using Cisco Local Director and
non-sticky sessions.
2) Has to be cookie-less.
Right now, I'm storing everything in a db and using a uuid as the session
token.
I'd rather just serialize/deserialize the CFCs that are being used because
it would be cleaner, but no dice. Just interested in what others may have
done along this line.
By all means, send me what you've got - I'd definitely be interested in
looking at it.
Jeff

I wrote a serialize, deserialize function based on a recommendation by
Barney, mine depends on method naming conventions which sux, but you can
look at it you like and get an idea for how mine works? Let me know.

Subject: [CFCDev] Serialization/De-Serialization of CFCs
In some brief experimentation, I found I could serialize a CFC using WDDX,
but de-serialization did not work.
Has anyone played around with this? Are there other techniques for
achieving persistence of CFCs across a cluster?
