<div dir="ltr">Hi Stuart,<div><br></div><div>Thanks for the upgrade handler fix. I can clearly see the handler is registered and handleRequest is called in a debug session. I also replaced EMPTY option with OptionMap.create(UndertowOptions.ENABLE_HTTP2, true) when opening client connection. The response protocol is still HTTP/1.1 for both http and https requests. The following is the output from the console and the syched/updated source code can be found </div><div><a

<br>
</span>You need to pass in the ENABLE_HTTP2 option in the OptionsMap. For<br>
http URI's this means that the client will attempt an upgrade on the<br>
first request, for https URI's ALPN will be used to try and negotiate<br>
HTTP/2. This is how browsers behave, and will work even if the target<br>
does not support HTTP/2.<br>
<br>
One thing I did notice that I fixed upstream was that the Undertow<br>
builder was not registering a HTTP2UpgradeHandler when HTTP/2 was<br>
enabled, which has been fixed.<br>

<br>
</span>I think this was probably caused by the lack of the upgrade handler<br>
(well for h2c, h2c-prior should still work).<br>
