didnt we cover this already?
with the same bit of code?
use duplicate() to create request scope values
you are right in saying that the code below makes pointers

Guys, its the pointer situation again!
I need you CF eyes.... a third party of mine has developed the following
code to copy session variables into the request scope. I believe that what
he is performing to be the copying of pointers and not actually 'copying'
the values to the request scope. Can you take a squizz and see what you
think? He is using CF4.5 so he has no StructAppend() or correct Duplicate()
function.
<cfcase value="session2request">
<cflock scope="SESSION" type="READONLY" timeout="15">
<cfloop collection="#session#" item="key">
<cfset request[key] = session[key]>
</cfloop>
</cflock>
</cfcase>
he is then referencing the code within a page as request.VARIABLE. I am
sure that these need to be locked since they are only pointers... what do
you think?
has anyone got a real world example of how to prove what I think is
happening? (since I know a lof you agree that it is a case of pointers!)
Many thanks
Neil
