A couple of questions that I can't
seem to sort out from reading the DOCS...
1. Why would one need to use cflock when WRITING session.variables ?
My impression

A couple of questions
I know we have discussed this a good bit lately but I am still needing some
understanding. In my application, I make MANY session variables. I use these
variables to check certain things on many pages. Because of the past threads on
this I have surrounded them with CFLOCK tags. NowCan

My impression is that:
Session.var is NOT shared
A user with 2 browser windows open both on your site, or if your site has
frames would be 2 situations where there could be a session var conflict.

Ok, what is the consequence for failing to lock a session variable? Right now it
appears that with some unlocked session variables that we have on an application that
we inherited, it appears to be generating some huge memory leaks in ColdFusion
whenever we're going through the application.

Exclusively lock all of your sets, and ReadOnly lock all of your reads
(references).
Just do it, it's not too tough. :)
Watch out for application variables too.

Locking needs to be handled on the back-end and not be dependant upon
programmers to behave themselves, especially

Thanks for the extensive explanation. A couple finer points
still aren't quite clear to me. When you say "will lock all
of your session vars", from the rest of your explanation, I
gather you don't mean all of the session variables from all
sessions in all applications running on the
Point well taken. There will be certain scenarios, as you have
outlined, where manual locking will always be important. Something as
fundamental and universal as variable locking should not be one of
them.

A couple of general questions regarding locking session variables (CF
4.0.1):
Does a CFLOCK with name="#session.sesionid#" only lock the variables in
memory for that particular session, or does it lock all session
variables for the application?
The CF 4.0.1 documentation for CFLOCK has the
It locks all of the CFLOCK blocks where name="#session.sessionid#".
Practically speaking, it locks all of the session variables for that
particular session.
