Source: apache2 Version: 2.4.25-3+deb9u3 Severity: wishlist It's unclear to me why the http2 module in the Apache2 debian package doesn't *actually* enable the http2 *protocol*.
Maybe I don't understand this right, but it seems to me that to enable http2 in apache/Debian, you need to do the following: a2enmod http2 But then also add some configuration blurb like this somewhere: Protocols h2 h2c http/1.1 The above configuration will enable HTTP/2 over TLS (h2) and HTTP/2 over TCP (h2c, cleartext) then keep the http/1.1 as a backwards-compatibility option. Why isn't this part of /etc/apache2/mods-available/http2.conf? It seems to me if you want to enable HTTP2 on the server, you'd expect this to just turn on as well. I can imagine that people may want to enable only on *some* virtual hosts, but then that config can be commented out or disabled and added to virtual host as needed. Or it can be disabled in the relevant vhosts as well. It could also be a good place to have, commented out, sample H2Push configurations as well... e.g. # # HTTP/2 push configuration # # H2Push on # # # Default Priority Rule # # H2PushPriority * After 16 # # # More complex ruleset: # # H2PushPriority * after # H2PushPriority text/css before # H2PushPriority image/jpeg after 32 # H2PushPriority image/png after 32 # H2PushPriority application/javascript interleaved # # # Configure some stylesheet and script to be pushed by the webserver # # <FilesMatch "\.html$"> # Header add Link "</style.css>; rel=preload; as=style" # Header add Link "</script.js>; rel=preload; as=script" # </FilesMatch> More sample configs are here: https://httpd.apache.org/docs/2.4/mod/mod_http2.html#h2pushpriority What do you think? -- System Information: Debian Release: 9.1 APT prefers stable APT policy: (500, 'stable'), (1, 'experimental'), (1, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_CA.UTF-8, LC_CTYPE=fr_CA.UTF-8 (charmap=UTF-8), LANGUAGE=fr_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system)
