Ah, sorry, Rocknbil, only saw your response after I typed mine...

OK, that looks a good option - many thanks, I'll give it a go...

EDIT: I'm fairly sure I've tried something similar to that already and the problem was that the environment variable is on the server side (if in Perl), no?

Which means I would have to differentiate the cookies for each user, which then brings up the problem of identifying the user from the browser without the user telling you directly.

Or is that total rubbish?
