That statement doesn't make any sense - how can an application *not* work with sticky sessions? That would mean it doesn't work on a single server... The issue here is that if you do not have sticky session, you have to be able to manage sessions that move between servers at will. That means that either: 1) you use client scope instead of session scope (with all the attendant restrictions) 2) you write your own session management based on cookies 3) you rely on session replication (and, if you're not on CF8, make sure you don't put CFCs in session scope - and if you are on CF8, make sure you don't put arrays in the CFCs that are in session scope - and whatever other restrictions there are) Session replication can introduce a *lot* of network overhead between your servers as they all try to keep each other's session data in sync (and that can lead to performance problems or latency and session failure anyway). I don't recommend session replication except in very, very specific situations (and I'd generally recommend you use an "enterprise" J2EE server that does replication in an intelligent way - i.e., not JRun). -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ "If you're not annoying somebody, you're not really alive." -- Margaret Atwood ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295144 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
