     50Note on HTTP/2
     51--------------
     52
     53HTTP/2 is supported with `mod_gnutls` but works correctly only if all
     54virtual hosts using `mod_gnutls` share the same `Protocols`
     55setting. This will be fixed in a future release, but will likely
     56require GnuTLS 3.6 or later.
     57
     58The technical reason is that using HTTP/2 requires ALPN (Application
     59Layer Protocol Negotiation) to be set up before GnuTLS parses the TLS
     60ClientHello message, but earlier hooks cannot use
     61`gnutls_server_name_get()` to retrieve SNI data for virtual host
     62selection.
