cftry

If any exceptions occur while processing the tag body, look for a cfcatch tag that handles the exception, and execute the code in the cfcatch tag body.

cfcatch

Execute code in the body of this tag if the exception caused by the code in the cftry tag body matches the exception type specified in this tag's attributes.

Used in cftry tag bodies only.

cfthrow

Generate a user-specified exception.

cfrethrow

Exit the current cfcatch block and generates a new exception of the same type.

Used only in cfcatch tag bodies.
