Exception
Exception only
In exception error handling pages, you can access the error variables that are also available to the
tag. See
cfcatch
with "cferror."
Note: If type = "exception" you can substitute the prefix cferror for Error; for example,
cferror.diagnostics, cferror.mailTo, or cferror.dateTime.
Example
<h3>cferror Example</h3>
<p>cferror lets you display custom HTML pages when errors occur. This lets you
maintain a consistent look and feel within the application even when
errors occur. No CFML can be displayed in the pages, except specialized
error variables.
<p>cftry/cfcatch is a more interactive way to handle CF errors within a CF page
than cferror, but cferror is a good safeguard against general errors.
<p>You can also use cferror within Application.cfm to specify error
handling responsibilities for an entire application.
<!--- Example of cferror call within a page --->
<cferror type = "REQUEST"
template = "request_err.cfm"
mailTo = "admin@mywebsite.com">
<!--- Example of the page to handle this error --->
<html>
<head>
<title>We're sorry -- An Error Occurred</title>
</head>
<body>
