Hi David, Thanks a lot for the suggestion.
Modifying recompiling the FTP Server is something I’d rather avoid to make sure we don’t have to maintain our version of the project. I will try the other idea instead, i.e. supply a modified version of FTPLoggingFilter to the FilterChain. I’ll report back here how it works out.
