Sorry, Dave. I guess I wasn't clear enuf. The original had "...it's intended..." referring to client scope.
My comment about "practicality" referred to client scope not to session scope. I was simply pointing out that it can be practical to use client scope. I did not mean to imply session variables were not practical. I was reacting to the suggestion that client scope was "intended more for long-term user data storage" I'm not exactly sure what the writer meant by this, but I didn't want the suggestion that client scope should not be used to maintain state to just lie there. As always, conclusions are application-dependent. In the application I spend most of my time on, every page has database queries, and the ms spent on pulling client variables out of a database is not where the time is being spent. In addition, I don't use the default client variable database storage method that requires parsing a #-delimited list to get each client variable. My client variable database has a specific column for each client variable. best, paul At 05:13 PM 12/14/02 -0500, you wrote: > > > The Client scope isn't really intended to behave the > > > same way as the Session scope - it's intended more > > > for long-term user data storage, rather than storing > > > data during an individual visit. > > > > It's intent is one thing.
