The CFABORT tag stops processing of a page at the tag location. ColdFusion simply returns everything that was processed before the CFABORT tag. CFABORT is often used with conditional logic to stop processing a page because of a particular condition.
<CFABORT SHOWERROR="text">
Optional. Specify the error you want to display when CFABORT executes. This error message appears in the standard ColdFusion error page.
<!--- this example demonstrates the use of CFABORT to stop the processing of a CFLOOP.
