To continue on what you said, "not every CFC is fully encapsulated", this is
using a CFC as more of a function library than an object in an OO world. Not
"best practices" as far as OO methods go, but still a fair use for a CFC
just to abstract a certain job.
Back to Merritt, I can easily set a session variable in a CFC just using
<cfset session.foo = "bar">. I'll send you some sample code if you need to
see it work.

Subject: RE: Session Variables in CFCs
If you have a fully encapsulated CFC it should be unaware of it's
environment in any way. Since the session scope is part of the CF
environment, CFCs shouldn't know about it. Generally the better route is
to
put the entire CFC in the session scope, and have the CFC only manupulate
instance variable (which are also in the session scope, because the whole
CFC is). That way the CFC doesn't need to know about the various CF
scopes.
This same thing applies to the application and server scopes as well.
Now, not every CFC is fully encapsulated. If you have a CFC who's task is
to manage authentication, it's almost required to set session (or client)
variables. The difference is that this CFC is setting the session
variables
for OTHER CODE to make use of (possibly CFCs, possibly not). It's not
setting them for IT'S INTERNAL USE.
Obviously that's a gross oversimplification of the whole situation, but
hopefully helps.
