Subject: isDefined() on session/application variables


Does anybody have any thoughts on weather you should always do an
isDefined() before reading or writing a session/application variable?  Why?


thanks,

tj

That is one of those golden rules of programming.
You cannot perform an operation on something that is not existant.
Therefore, you must ensure that your variable exists before you can use
it. Much like initalizing your variable you must also always be sure it
exists
given the nature of ColdFusion :)
