Hi I just had a play around with the new draft HTTP2 support in Curl/libcurl. For the most part it works great, however Google's web server GFE/2.0 does not seem to like it when attempting to connect over a non-secure connection. This is easily reproduced with the following command, which produces the output attached: curl -v --http2 http://www.google.co.uk
As you can see, GFE returns HTTP error 400. When connecting over a secure connection, however, it works as expected. I assume this is because Google isn't up-to-date with the latest draft spec? Can anything be done with libcurl to workaround the error? If it was just Google it wouldn't be a problem, but http://www.blogspot.co.uk uses the same server software and there's no secure alternative on that. Regards Chris
