Hi, to activate HTTP2.0 on ISPConfig 3.1 (Debian 10) can i basically just follow this description? https://www.howtoforge.com/how-to-enable-http-2-in-apache/ Dont do I have to take anything into account because of ispconfig? And the last question, when I do not activate SPDY/HTTP2 in ispconfig is there still http1 available? Regards
That looks about right, it's pretty simple; instructions have been posted in the forums here in the past. I'd also uninstall mod_php since you're not using it. Not much. It's probably easier to set Protocols in a separate conf file, eg. create /etc/apache2/conf-available/http2.conf with: Code: <IfModule mod_http2.c> Protocols h2 h2c http/1.1 </IfModule> Then run a2enconf http2. I may not understand your question, but yes, it uses http1 by default, if you don't enable http2, that's what you're using.
Ok thank you!, I followed the posted instructions as it was and just enabled SPDY/Https2 in the ispconfig Server config. And it already looks like it works. I also got the follwing http2.conf file as default Code: <IfModule !mpm_prefork> Protocols h2 h2c http/1.1 # # 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> # Since mod_http2 doesn't support the mod_logio module (which provide the %O format), # you may want to change your LogFormat directive as follow: # # LogFormat "%v:%p %h %l %u %t \"%r\" %>s %B \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined # LogFormat "%h %l %u %t \"%r\" %>s %B \"%{Referer}i\" \"%{User-Agent}i\"" combined # LogFormat "%h %l %u %t \"%r\" %>s %B" common </IfModule> When i check my vhost config though after activating http2 i find this Code: Protocols h2 http/1.1 SSLProtocol All -SSLv2 -SSLv3 looks like i am missing this h2c is this a problem? Update: I read a little bit about it, looks like h2c is just the non ssl version of http2 so its actually fine only to have h2 on a ssl site
