When KeepAliveDuringTransfer is enabled and a connection is made to Wing FTP Server (v8.2.5 for Windows), an upload error occurs if a KeepAlive signal is sent during the upload process.
Sending a NOOP command results in the following server response:
"Another command is pending currently, please try again later (451)"
Currently, Rebex FTP 8.0 recognizes the message "Another command is currently pending" as a success, but it fails to recognize "Another command is pending currently."
It would be better to implement a more flexible check.
For example:
StartWith("Another command") && StartWith("pending")
Thank you
