I generally would keep the variable as long as you need it and no longer. If it's just needed for the request, there is no reason at all it should be in the session scope. Performance is a concern, but so is data leaking from page to page. If you're putting alot in session and not paying attention to the names then you may end up stepping on variables as you go.
At the least, if they are needed for a multipart form (for example) then he should be clearing (structDelete()) the variables when they are no longer needed. Better yet, put then in a struct in session and just nuke that struct when you're done with it. IF you have: session.myform.firstname session.myform.lastname session.myform.phone Then when you are done just do a little structDelete(session,'myform') action and your session is all clean again. -Cameron On Tue, Jan 31, 2012 at 11:01 AM, Robert Harrison < rob...@austin-williams.com> wrote: > > I'm an old school programmer who watches every bit and byte and really > practices resource management in my coding practices. > > I've got a new programmer working for me (on contract) and I'm finding > he's using session Vars all over the place.
