Re: [jetty-dev] server with jetty 9.4.2 no longer accessible from iPhone

[Michele Rossi <michele.rossi@xxxxxxxxx>]

thanks a lot Simone.

If I simply remove the line 

jetty.alpn.protocols=h2-17,h2-16,h2-15,h2-14,h2,http/1.1

from my start.ini then everything works well again.

I am no longer sure why I had that line there in the first place.

thanks,

Michele

In 9.4.x we switched to only providing "h2" because most browsers have
picked it up (HTTP/2 is now 2 years old) and draft versions are not
used (much) anymore.

Apparently, iPhone does not keep the pace with others.

What you can do is to specify in jetty-http2.xml the second parameter
to HTTP2ServerConnectionFactory, and reintroduce support for draft
versions.

Right now it is:

<New class="org.eclipse.jetty.http2.server.HTTP2ServerConnectionFactory">
  <Arg name="config"><Ref refid="sslHttpConfig"/></Arg>
  ...

You want it to be:

<New class="org.eclipse.jetty.http2.server.HTTP2ServerConnectionFactory">
  <Arg name="config"><Ref refid="sslHttpConfig"/></Arg>
  <Arg>
    <Array type="String">
      <Item>h2</Item>
      <Item>h2-16</Item>
    </Array>
  </Arg>
  ...
