Hi there.

You need to enable the "http2" feature in varnish:
https://varnish-cache.org/docs/trunk/reference/varnishd.html#feature

either at runtime using "-p feature=+http2" in the varnishd command line,
or using "varnishadm param.set feature +http2" if varnish is already
running. Note that the varnishadm method won't survive a restart.

Hi Guillaume,

Thanks for your reply ;)

Is varnish http2 feature ready for a production server? Or is it still
experimental?

Would I need to setup Hitch for http2, too?

# Enable to let clients negotiate HTTP/2 with ALPN. (default off)
# alpn-protos = "http/2, http/1.1"

thanks & greetings
Becki

it's ready. And yes, I think you need to enable it on hitch too.

Hello Guillaume,

thanks again for your reply

ok ... did enable hitch ALPN

alpn-protos = "http/2, http/1.1"

did enable http/2 in varnish.

I'm running opensuse and it has its configuration in /etc/sysnconfig/varnish

VARNISHD_PARAMS="-j unix,user=varnish -f /etc/varnish/main.vcl -a :80 -a
127.0.0.1:6086,PROXY -T localhost:6082 -s default=malloc,2G -s
static=file,/var/cache/varnish,5G -p feature=+http2"

which then is loaded via systemd service

[Service]
EnvironmentFile=/etc/sysconfig/varnish
PIDFile=/var/run/varnishd.pid
ExecStart=/usr/sbin/varnishd -P /var/run/varnishd.pid -F $VARNISHD_PARAMS

restart hitch & varnish

if I look in the logs all looks fine

https://tools.keycdn.com/http2-test

https://http2.pro/check?url=https%3A//kohphangannews.org/

It's called h2 for ALPN, and with that I think you should be good.

Hello Dridi,

thanks a lot for that hint. Not sure how http/2 made it into the config?
changing to h2 finally did the trick and now http/2 is working with
varnish ;)

thanks & all the best wishes
Becki
