Here is what I have done to implement the Site Shutdown use case. Create an application level status variable, called runStatus, with a default value of 'started'.
Create a page where the application admin user can initiate the shutdown process. Enter the number X of minutes before shutdown. RunStatus is set to 'shutting down'. A timer is started which will run the shutdown process in X minutes (whatever the admin entered as a value). New Sessions: When RunStatus != 'started', all login attempts are automatically redirected to an information page. Current Sessions: If RunStatus = 'started', do normal action. If RunStatus = 'shutting down', display a 'System shutting down in X minutes' message before doing the normal action. If RunStatus = 'stopped', send user to information page and kill session. Shutdown Process: After X minutes, set RunStatus = 'stopped'. Then do whatever needs doing, like closing database connection pool, notifying admin user, etc. Wiebe de Jong -----Original Message----- From: Dean A.

I have a website I'm working on that is fairly typical (I think): there areoperations that anyone can do and operations that require a user to be logged in. Authorization and authentication are done using a database. From time to time, the site needs to be shutdown for general maintenance, upgrades, etc. I want to give the users fair warning that the site will be shut down at such and such a time. I also want to prevent the users from performing operations during this "shutdown". I think it would be good if there were still a home page up, with indications that the system is offline and should be back by a certain time. At first I thought I would create some table in my database to control some of this but I think this is not such a great idea, as the reason for taking the site down may be to do something radical to the database. Is there some "best practice" for accomplishing this? Thanks.
