I just tried with our own https://webtide.com website, which also does TLS in Jetty, and have no problems downloading large files, for both Firefox and Chrome on Linux. We did not hear any other similar report. Just a note that HTTP/2 does not use chunked transfer coding (which is a HTTP/1.1 only feature). Would be great if you can reproduce and report the server DEBUG logs. You can also look at what happens on the client; in Chrome, open: chrome://net-internals/#http2 There you will see a list of connections that use HTTP/2. Identify that of your server, and you will see the events for that connection. Report that event list, which should contain the frames that the client sent and those received by the server. We should be able to see something abnormal there. -- Simone Bordet ---- http://cometd.org http://webtide.com Developer advice, training, services and support from the Jetty & CometD experts. _______________________________________________ jetty-users mailing list [email protected] To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/jetty-users
