Custom 404's are a good idea -- the only content I need in the directory is the 404 maintenance page itself. I can just swap the names of the actual webapp and 'maintenence' webapp directories (they're exploded). Thanks to everyone for the other good suggestions.

Site down for maintenance senario
Is there a straightforward way to toggle or add something in Tomcat, in the event a webapp is intentionally taken 'offline for maintenance"? The user would receive the same single notification page saying as much, for any and all requests. Tomcat 7.0.42
