Try using cftry tag:

FTP code here.

    <cfcatch type="exception type1">
        Add exception processing code here.
    </cfcatch>

    <cfcatch type="exception type2">
        Add exception processing code here.
    </cfcatch>

    <cfcatch type="Any">
        Add exception processing code appropriate for all other exceptions here.
    </cfcatch>

</cftry>

Exception handling isn't going to help you if your request is served by the targeted webserver. Exceptions are only thrown if something unexpected occures while trying to send the request by ColdFusion, ie outgoing firewall blocks your request or any other kind of connection issue.

The only thing you need is the CFHTTP struct variable that is always generated after calling the tag. This struct contains all data related to the actual HTTP response. (Keeping the request within <cftry>/<cfcatch> is still suggested though.)
