Rethrows the currently active exception. Preserves the exception's cfcatch.type and cfcatch.tagContext variable values.

Use this tag within a cfcatch block. This tag is useful in error handling code, if the error handler cannot handle an error that it catches. For example, if cfcatch type = "any" gets a DATABASE exception, and the code is designed to handle only CFX exceptions, the handler raises the exceptions again, with details intact, so that a higher-level handler can process the error information. If you used the cfthrow tag, the type and details of the original exception would be lost.

exception. --->
