Using the FTP Session Log

See more FTP Examples

The Chilkat FTP component can keep a session log if the KeepSessionLog property is turned on. This is helpful in debugging problems. Chilkat support will usually ask for a session log when working to resolve your problem, because it contains a log of the exact commands sent to the FTP server, and the exact responses received.
