I got into a debate with a system guy today who told me they were
storing their session vars in the SQL database.  I insisted he'd got
his terminology wrong and in fact it was client vars he's storing not
session vars.

He was adamant.  No, it's definitely session vars stored there.  

Not only that,  he said that they had a lot of sessions (for example
50,000 sessions last month) and if they locked them all every time
they accessed them, the server would crawl to a halt.     He left me
in no doubt ... i was NOT to lock session variables, either reading
them or writing them, and that the were stored in the database.

Do you he's got it right?

The environment is multiple load-sharing Win2000 servers, CF5.

My understanding of it all was that you ALWAYs locked session vars. 
If you're reading them, use a readonly lock, if you're changing them,
use an exclusive lock.  And that session vars are always stored in
server RAM.  Not so?
