Though, if you expect there to be a time when NO ONE is using your app, I have to assume the scale of users isn't huge. So (assuming your app's relatively small and limited to one server) in your case the easiest way may be to use the application scope. If you have multiple CF servers, you can do this same thing using the database. Each time a user requests a page, update a variable. This can be something very simple such as: application.lastVisit = now(); Then you can just test how long it's been since application.lastVisit and compare it to your session timeout. If the last visit was longer ago than the timespan of your session timeout, you can be sure nobody is logged in. You'll probably want to make sure you are only triggering this for logged in users (not when Google comes knocking). You'll presumably also want to exclude yourself from this since you will be logged into the admin at the time (one user). though, I suppose if you expect to uncheck this box you will already have devised a way to get into the app which this blockade is in place. If you really want to get fancy with it, instead of a checkbox you could enter the date/time that you'd like to conduct maintenance in the admin. Use this in your code to start warning users as the login for an hour or two before the maintenance. Then 15 minutes before that time, start blocking new logins and warning currently logged in users that they need to complete their work. Then when the time comes, throw up the wall for everyone. -Cameron -- Cameron Childress -- p: 678.637.5072 im: cameroncf facebook <http://www.facebook.com/cameroncf> | twitter<http://twitter.com/cameronc> | google+ <https://profiles.google.com/u/0/117829379451708140985> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:353743 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
