The SessionOptions class documentation (https://winscp.net/eng/docs/library_sessionoptions) seem to show neither the
"Optimize connection buffer" on/off, nor the session Keepalive options options, nor how to use them in code/script, if they are present.
I'm having issues transferring large files, which I can mitigate, by manually setting the the Optimize connection buffer to off, in the GUI, and may be able to further avoid, by playing around with Keepalives. The problem is that the real way that I actually use WinSCP is via a powershell script, and it appears that neither of those options are available, since they are not present in the SessionOptions class, or at least not documented.
Please reply with or point me to info on those options, if they do exist, or otherwise, please implement them, so that WinSCP is fully usable via scripting/API. Thanks a lot, Ralph.
