Hi As Jetty doesn't support sending CONTINUATION frames explicitly from the API. I am going to develop it by myself to support my research.
I reviewed your implementations on how to sending priority frame and ping frame. It seems that we can do this by adding an interface in Session, and implement it in Http2Session by using control(stream, callback, frame); I also find that there is no continuation frame in the package org.eclipse.jetty.http2.frames. Does that mean I also need to write a construct method of continuation frame. Hope you can give me some hint or suggestions. Thank you so much.
