The first thing you should do is write (or google for) a top level error template that emails you all the popular scopes (session, url, form, cgi ...) along with any other application info that might be useful (the current user ...). Set this as the global error handler either in Application.cfm or the ColdFusion administrator). As to try/catch/throw: I think it's only worth catching something if you can recover from it, or you really want to show a specific error to the end user - typicaly file not found errors will only happen during dev. or inital set-up, for instance, when you'll have robust exceptions turned on anyway. I tend to throw errors when parsing configuration files, for instance, and not bother trapping them. -- Tom Chiverton Helping to authoritatively leverage exceptional mindshares **************************************************** This email is sent for and on behalf of Halliwells LLP.
