Ah yes, I actually did know that (honest!) but it had escaped me... :) > <cfdump var="#foobar.getPagePath()#"> Ooh, nice, I like that. :) So combining both the above, doing something like this would return a unique reference to a function: <cfset key = myFuncRef.getPagePath().hashcode()> Cool. The only (slight) disadvantage I see with this is if the body of the function changes then you'll still get the "old" cached version (at least until the cache times out), because the hash code doesn't change; using a straight myFuncRef.hashCode() call will guarantee that ant change in the CFM page holding the function will also change the function hash code and so will be "re-cached". Also, it's an additional method call over a straight myFuncRef.hashCode() call... Good points to think about, cheers Matt.
