re: Trying to understand application.cfc...
I do exactly that, Rick, and it works fine. All my app vars are set in onApplicationStart, except for the constants like 'name', which I set outside the methods: cfcomponent output=false cfscript this.name = myAppName; this.applicationTimeout = createTimeSpan(0, 8, 0, 0); ... /cfscript cffunction name = onApplicationStart cfset application.dsn= myDatasource /cffunction From: Rick Faircloth r...@whitestonemedia.com Sent: Thursday, August 12, 2010 2:10 PM To: cf-talk cf-talk@houseoffusion.com Subject: Trying to understand application.cfc... Ok...I worked with application.cfc's for awhile and things seemed to work fine, but then I had some issues and went back to old reliable application.cfm. Now, however, I'd like to try again to get a grasp on how to use application.cfc's. First question: Why can I set the application.website variable like this: cffunction name = onRequestStart cfset application.website = RickFaircloth.com /cffunction But not like this: cffunction name = onApplicationStart cfset application.website = RickFaircloth.com /cffunction ??? OnApplicationStart would seem to be a more logical place to set a global variable for an entire application than onRequestStart.

RE: Trying to understand application.cfc...
Thanks for the reply, Jason... Well...I swear, the first time I tried to set application.website inside onApplicationStart, I got an error saying application.website wasn't defined. Now, for some reason, it works. The only thing I added was output=false as you have in your example. At first, I used: cfcomponent cfset this.name = siteManager cfset this.sessionManagement = true cfset this.sessionTimeout = #createTimeSpan(0,1,0,0)# cfset this.applicationTimeout = #createTimeSpan(1,0,0,0)# cffunction name = onApplicationStart cfset application.website = RickFaircloth.com /cffunction /cfcomponent Any wrong or missing? -Original Message- From: Jason Fisher [mailto:ja...@wanax.com] Sent: Thursday, August 12, 2010 2:17 PM To: cf-talk Subject: re: Trying to understand application.cfc...

Re: Trying to understand application.cfc...
You should be able to set that variable in OnApplicationStart() with no problems. In fact, as you said, that's the preferred place to set it. You must have something else going on that's causing the problem.

RE: Trying to understand application.cfc...
Rick, Is it highly possible that you had run the application, and then placed that code into onApplicationStart? If this is the case then the undefined variable would make sense, and why it works for you now.

RE: Trying to understand application.cfc...
Rick, One thing I do is to place a piece of code into the onRequestStart method to reinit the application variables. This will let you set variables in the onApplicationStart method and be able to change them without having to restart ColdFusion or wait for the application to timeout. In you onRequestStart() function, place the following: cfif StructKeyExists(URL, reinit) cfscript OnApplicationStart(); /cfscript /cfif Then, call your website like http://www.yourwebsite.com?reinit=1 This will allow you to update your Application scoped variables if you have them all set up in the onApplicationStart() function.
