Hello,
I have a strange problem (definitely some kind of my own ignorance) :
If I try to access anything on the site https://www.samba.org WITHOUT
proxy, my browser negotiate happily for http/2 protocol and receives all
the data. For?http://www.samba.org WITHOUT proxy it starts with http/1.1
which is auto-redirected from http to https and continues with http/2.
So far so good.
But WITH proxy, it happens that squid is using http/1.0.
That is odd. Squid should always be sending requests as HTTP/1.1.
Have a look at the debug level "11,2" cache.log records to see if Squid
is actually sending 1.0 or if it is just relaying CONNECT requests with
possibly HTTP/1.0 inside.
Hello,
here are the debug logs (IP addresses redacted) after connection attempt
to https://samba.org/ :

So, it seems it's not true that squid is using http/1.0, but the guy on
the other side told me so. According to the log, do you think I can
somehow make it working or is it definitely problem on the samba.org
webserver?
Thanks again,
