You want _one_ user to have access to it? Pseudo-code.cfm
application.cfm:
<cflock scope="application" type="exclusive" timeout=30>
<cfif isDefined("application.inUse") and
dateDiff("n",application.lastHIt,now()) lte 30>
<cfoutput>
Sorry, this app is in use.
</cfoutput>
</cfif>
if date diff gte 30, remove application.inuse
</cflock>
Have a login screen here, and before you log them in, do another
exclusive lock check to make sure it's ok, log them in, set
application.inUse = true.
At the bottom, do application.lastHit = now()>
So, basically, our code checks for an application var _as well as_
checks to see the last time the user hit the site. If it was more than
30 minutes ago, we 'unlock' the application.
