Ok, what if you are using application variables as a part of the IF
statement and session in the IF? e.g:
<CFIF Application.Foo>
<CFSET Session.bar = 1>
</CFIF>
Is it ok to nest different types of Locks (session and application). And
what if Application.foo was actually session.foo? Would I need nested
session lock-ing or will the outer Lock around the if statement lock all
session variables with in?

If you're doing something like this:
<cfif IsDefined("Session.Foo")>
then it should be locked. On the other hand, if you're just referencing a
session variable within a CFIF:
<cfif Variables.Foo IS "bar">
<cfset Session.Foo = "baz">
</cfif>
then you could put the CFLOCK within the CFIF.
Lock 'em, Dano!
