We've managed to get the server to work using HTTP or HTTPS but we're unable to recieve the data correctly when using SPDY.
We run the server with the following command: sudo ./flip_in_mem_edsm_server --spdy-server="0.0.0.0, 443, cert.pem, key.pem" --logdest=file --logfile=/tmp/flip_log.txt --v=2 --force_spdy
When doing a request from Chromium, which we run with option --use-spdy=ssl, we get ERR_SPDY_PROTOCOL_ERROR. From the server's side things
seem to be OK, and running Wireshark on the client shows responses from
the server with encrypted data. On the chrome://net-internals/#spdy page we see that we recieve frames but the data recieved is unacked. (see attached image)
I'm atttaching the log from the flip server. It is quite large as it has some of our own debug messages included, but maybe it has some value.
