Hi Oleg, Thank you very much for your quick reply.
I looked at the example, ZeroCopyPost.java and its super class BaseZeroCopyRequestProducer. As you described, produceContent can be called multiple times when underlying I/O session gets ready to send more data. I wrote a loop code inside the produceContent, and it was the cause of this issue. After I fixed the code to let the framework handle that, data is sent correctly! I updated the Gist with the corrected implementation. https://gist.github.com/ijokarumawak/6027ca64eb28fd143acd173d799ffd48 Thanks again for this great product and your help :) Koji > On Fri, 2016-08-12 at 13:02 +0900, Koji Kawamura wrote: > > Hello httpclient community, > > > > I'm having an issue with HTTPS and HttpAsyncRequestProducer > > combination, so I would like to ask for some help. > > > > I've been using httpclient HttpAsyncRequestProducer to make a > > non-blocking HTTP POST request. > > My use case consists of two threads, one is pushing data to a channel, > > and the other is reading streaming data from that channel, then > > producing a POST chunked content. > > > > It's been working wonderfully with HTTP, but when I tested with HTTPS, > > noticed it only sends first few KB of data, even if I'm using the same > > client code. > > If the whole data size is less that about 8KB, it works, but bigger > > than that, further data is not sent. > > > > Debugging around AbstractContentEncoder and SSLIOSession, but I > > couldn't find the exact cause of this behavior yet.
