Hi,

Thanks for reply. So when data flow from Proxy Buffer to Send Buffer stops? From some other articles I was under impression that Send Buffer only contains data that was send to the client but unacknowledged - is that not true?

Is Send Buffer filled with both send/unacknowledged data and data not send at all?

Nagle usage in this question was only attempt to simplify data flow :-), so I am more interested how and when data is passed from Proxy to Send Buffer.
