    Looking for way to get the SITE ftp command.  I am uploading a file at work to our MVS aka z/OS mainframe FTP Server.  I need to set up some record length and format parameters on the server.   I.e. quote LITERAL SITE LRECL=1100 RECFM=FB TRACKS PRIMARY=10 SECONDARY=5 This needs to be set before I send a file from the PC. Thanks for any suggestions!

    Hi All, I have a couple of questions.

  1. Is there any negative impact of using keepAlive = true, when i need to download multiple file, should i set the keepAlive as false for the last call ?
  2. Setting KeepAlive = true, does it impact the ftp server throughput by keeping any port/connection open ?
