36: * The only purpose of this class is to hold onto an instance of
37: * FtpClient to prevent the FtpClient from being garbage collected.
38: * If the client gets collected it will close the command stream
39: * which will cause the remote ftp daemon to close its outputstream
40: * which will cause and EOF on this inputstream on our end.
41: *
42: * The real answer is to re-architect all this stuff to not open an
43: * ftp connection each time the user needs something from the remote
44: * side. The other correct thing it to totally ignore all the ftp
45: * client stuff and just use the ftp proxy stuff in the CERN HTTP
46: * server.
