It's really the same thing except sessions are more automagic. The main differences are that you of course reduce some overhead if you only need certain vars on certain pages or if you need them infrequently then you can store/retrieve them yourself. As far as a large amount of large objects, if you don't need them every page load then you may want to look at stuffing them in a db and only retrieving then when needed. -- Thanks! -Shawn http://www.spidean.com
