Using the cfrethrow tag

The cfrethrow tag lets you create a hierarchy of error handlers. It tells ColdFusion to exit the current cfcatch block and “rethrow” the exception to the next level of error handler. Thus, if an error handler designed for a specific type of error cannot handle the error, it can rethrow the error to a more general-purpose error handler. The cfrethrow tag can only be used in a cfcatch tag body.
