it will remain cached until the cache expires. once the cache expires, the next person to run it will cache it again. i probably phrased it a bit ambiguously. what i meant was that in the time it takes to load the page initially and for the user to have a quick look then refresh the page, the timeout will have expired if it's set to a few seconds. Therefore for one particular user, employing query caching with a very short timespan will not affect the validity (up-to-datedness - i never was particularly good at grammar) of the data that is being displayed, so you don't have to worry about refreshing your cache after every update/insert/deletion. But it will improve the performance of your site (if it's heavily loaded), because any other users that request the same query in that short timespan will get the cached dataset returned.

I always presumed that the caching timeout was reset every time the query is called. Are you saying that the person who calls the query initially (while it is not cached) is the only one that can reset the timeout? In other words, what you appear to be saying is that person A caches the query (set to 4 seconds). B calls it 1 second later (still cached), C calls 1 second later (still cached), D calls it 1 second later (still cached), E calls it 1 seconds later (still cached), A calls again it 1 second later and it is no longer cached? I thought that if it is called every second it will stay cached indefinitely (or until it becomes the last query in the maximum number of queries to cache) no matter who calls it. Can anyone else verify which is correct? -- Bud Schneehagen - Tropical Web Creations _/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/_/ ColdFusion Solutions / eCommerce Development [EMAIL PROTECTED] http://www.twcreations.com/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Your ad could be here.
