If this is software that's intended for consumption by other companies, I
would recommend this in your application.cfm
<cflock scope="session" type="readonly" timeout="20">
<cfset request.session = duplicate(session)>
</cflock>
Then make all reverences to session. ( as above ) within the rest of your
templates to request.session instead. This prevents you having to fill the
application up with tons of cflock tags and ensures that the app will work
on someone else's server, even if they have full-checking enabled in the cf
administrator. This is also a good way to easily ( little code ) shore up
those leaky session variables prior to CF MX.
If this is software intended solely for internal consumption, you can get
better performance by name locking individual variables or routines,
although it requires more code, and afaik there's still the risk of leaky
session vars prior to MX.
