Dear Graham, Thanks for the quick answer! Basicly, I would like to handle this problem from the app, so I can't modify the underlying architecture. Your suggestion needs some changes in the apache configuration, I guess. The only thing I have access to is the source of the webapp. Thanks, anyway, and if you have hints for the single instance solution too, please share.
