Being that you have stored them in the request scope, the CFIFs are pointless since the request scope is NOT persistent. I store settings such as the applications database name in the application scope since it is global to all requests and does not change for the app. I also store CFCs in the application scope.

However, since I'm not completely familiar with how this all works, Am I creating large amounts of overhead to the server for this convenience? I wouldn't think so since I'm not calling any major methods yet but maybe there is more going on? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion 8 - Build next generation apps today, with easy PDF and Ajax features - download now http://download.macromedia.com/pub/labs/coldfusion/cf8_beta_whatsnew_052907.pdf Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:288918 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
