Just to clarify what I think Micha means... If you have code in Application.cfm that says: <cfapplication name="someapp" .../> <cfif not structKeyExists(application,'init')> <cflock scope="application" type="exclusive" timeout="10"> .... do a bunch of application init ... </cflock> </cfif> <cfif not structKeyExists(session,'user')> <cflock scope="application" type="exclusive" timeout="10"> .... do a bunch of session init ... </cflock> </cfif> .... a bunch of variables / request setup ... When you change this to Application.cfc you'll end up with: <cfcomponent> <cfset this.name = "someapp"> .... <cffunction name="onApplicationStart"> .... do a bunch of application init ... </cffunction> <cffunction name="onSessionStart"> .... do a bunch of session init ... </cffunction> <cffunction name="onRequest"> <cfargument name="targetPage"> .... a bunch of variables / request setup ... <cfinclude template="#targetPage#"> </cffunction> </cfcomponent> Note several things: 1. you no longer need to lock 2. you no longer need to test for app / session init on every request - CF does it automatically 3. only onRequest is called on every request - onApplicationStart is called just once per application and onSessionStart is called just once per session. So overall you gain performance from not having tests for app / session but you lose performance for a function call and an include. I think it's a small price to pay for the benefits of cleaner initialization. -- Sean A Corfield -- http://www.corfield.org/ Team Fusebox -- http://www.fusebox.org/ Breeze Me! -- http://www.corfield.org/breezeme Got Gmail? -- I have 49, yes 49, invites to give away!
