I thought this was a standard way of storing user information? I've copied an example at the bottom (this application calculates quotes for a sailmaker)

I'm not sure what else I could use?

>but the 2nd rule of session hashes is don't write them to disk - that is really inefficient. Look at using something like MySQL,

Actually, I serialize the data and store it into a Postgresql table. This is what I meant by writing to disk. I suppose some caching by Postgresql helps here?

I'll have a look, thanks
