Re: [CFCDev] Best way to dynamically change method bodies (from "CFINCLUDE forces var scope into arguments?")

[Matt Liotta]

First, create your base DB component and however many child components 
you need for each specific DB. Then, create a session save component 
that will take care of saving your session to your DB. This is done by 
the session save component deciding which DB component to use and 
calling the appropriate methods. I would recommend that the session 
save component read from a configuration file which DB component to 
use.

I could be doing that wrong, of course.

As it stands there is a lot of information gathered during a user's 
session.
I collect a bunch of information about their User Agent, track all the 
pages
of the application that they've visited (their "Clickstream"), and so 
forth.

Once the session expires/times out this information is stored in a 
database
for later use by application metrics.  This is done via a
"DP_Session.save()" method (I know that many people prefer "persist()" 
but
they do the same thing).

Right now this method injects DB-specific code into itself using 
CFINCLUDE
and the DB type (as defined in an application-level component,
DP_Application).

Most of this was built specifically to address CF's inability to take
"end-of-session" action, but there are other reasons.
I'm now trying to determine (in the light of the 
CFINCLUDE-inside-a-method
issue) how best to modify this code to ensure thread-safety.
