Re: logging a user out (thanks)

Many thanks Ralph.

I'll post the solution if I find an elegant one - I just like the idea that
a user goes away for lunch and comes back to see that they've been logged
out, without clicking a link to try to carry on what they were doing.

beans are on the server side.

For that what you wan't you need either an applet
