Matt, Thanks for all that information. The article has good stuff in it.
My problem is that I have both 2 and 3 implemented. It seems that 2 never hits unless I turn off 3. Is that expected, or is there a way around it?

Please click here try again."). You typically surround portions of code but not entire templates in try/catch blocks, as you need a try/catch block per template otherwise. 2. The cferror tag, specifically this variant of it: <cferror type="EXCEPTION" template="/my/error_catcher.cfm"> should be used to house your application-wide error handler, which you build. The thing that kicks in to tell you when something has exploded. This can do nearly the same thing as a site-wide handler, or behave in some application-specific fashion. Its all up to you. I put my cferror statement in /Application.cfm. 3. The site-wide error handler bats cleanup in case neither of the above are in place, or they fail for some reason. I wrote a tutorial on doing a SWEH that is easily adapted to a cferror handler. It dumps all data scopes securely to disk, to screen or to email. The dumps are invaluable in problem diagnosis. You can write simple code that dumps error data to screen for a certain range of IPs or logins or whatever so the same handler works for developers or visitors. http://mysecretbase.com/Building_A_ColdFusion_Error_Handler.cfm -- [EMAIL PROTECTED] Janitor, MSB Web Systems mysecretbase.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:240167 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
