Exceptions
In the Administrator, when Exception Information is selected on the Debugging Settings page, the debugging output
includes a list of all ColdFusion exceptions raised in processing the application page.
The exception information includes information about any application exceptions that are caught and handled by
your application code or by ColdFusion.
Exceptions represent events that disrupt the normal flow of an application. You should catch and, whenever possible,
recover from foreseeable exceptions in your application, as described in
might also want to be alerted to caught exceptions when you are debugging your application. For example, if a file is
missing, your application can catch the
exception information in the debugging output, you can immediately see when this happens.
Trace points

Scope variables
In the Administrator, when the Variables option and one or more variable scopes are selected on the Debugging
Settings page, the debugging output displays the values of all variables in the selected scopes. The debugging output
displays the values that result after all processing of the current page.
By displaying selected scope variables you can determine the effects of processing on persistent scope variables, such
as application variables. This can help you locate problems that do not generate exceptions.
The Form, URL, and CGI scopes are useful for inspecting the state of a request. They let you inspect parameters that
affect page behavior, as follows:
Identify the HTTP request parameters.
URL variables
Identify the form fields posted to an action page.
