Just a quick update to say I updated the github code to remove the
HttpHandler and build responses via the Jersey annotated resource class,
the code should be simpler to follow.
Everything starts but I don't see SPDY protocol enabled (I'm using the
Chrome "HTTP/2 and SPDY indicator" plugin to test this).
Is there anything extra I need to do from the client or server sides?
Maybe setting HTTP headers or something else to initiate the protocol?
Any help would be greatly appreciated.
