Rebex incorrectly recognizes NOOP 200 server response as premature transfer success

Question

Hello,

I'm using NOOP command during transfers (KeepAliveDuringTransfer option) to avoid control connection being closed by routers/modems of our users leading to a timeouted transfer.

However, one of the servers responds with "200 I successfully done nothin'." and Rebex considers it a successfull transfer marker and throws an FtpException with a "Premature success response was received from the server even though the upload is still in progress" message.

Please add handling for this specific message (ignore it) :)

Thank you.

Thanks for letting us know, detecting NOOP responses is quite tricky. We added this message to the ignore list.
