Chapter 1: ColdFusion Tags 37
MAILTO
Optional. The email address of the administrator who should be notified of the
error. This value is available to your custom error page using the MailTo property
of the error object, such as #Error.MailTo#.
EXCEPTION
Required if the type is specified as Exception or Monitor. The type of exception.
Usage The CFERROR tag is normally used to customize the error messages for all the pages in
an application. As a result, you generally embed it in the
Application.cfm file. For
more information about the
Application.cfm file, refer to Developing Web
Applications with ColdFusion.
To help ensure that error pages display successfully, pages you specify with CFERROR
should not be encoded with the
cfencode utility.
CFERROR Error Variables
The exception-handling template specified in the TEMPLATE attribute of the
CFERROR tag may contain one or more error variables, which will be substituted by
ColdFusion when an error is displayed.

Request
This template can include only the error variables
described in the table under CFERROR Error
Variables and cannot include CFML tags. It
Validation
A validation error handler. It handles data input
validation errors that occur when submitting a form.
It is useful only if placed inside the Application.cfm
file.
Monitor
An exception-monitoring template is dynamically
invoked by the CFML language processor when it
first detects an exception condition, before it
searches for <CFTRY>/<CFCATCH> or <CFERROR>
handlers for the exception.
Exception-monitoring templates are useful for
monitoring and debugging exception handling
within complex applications.
