Varnish caching issue

[Amadeco]

Hello @magenx,

Thank you for this repository,

I am using this one for quite a long time, but I would like to ask you something,

I was activating your solution for drilling layered navigation by bots (extra_protect.conf) but the condition (your regex) was sometime working sometime not.

The issue seems to be related to varnish which can cache the HTTP request from only ONE side (no difference between robots or visitor by default) with the default configuration of Magento 2 (VCL config files).

Magento-nginx-config/magento2/sites-available/magento2.conf

Line 89 in 7318bba

include conf_m2/extra_protect.conf;

As HTTPS (TLS/SSL protocol) is a mandatory now, every request pass by port 443 by default

So I was wandering why some portions of the code from conf_m2 directories to the port 8080 was not added to the server port 443 in the config file of default sites-available magento2.conf. In particular, error_page.conf and some of this one : extra_protect.conf.

I did a test with an extension which can allow me to change the user-agent from my navigator and with the moving of the config files to the right server config, it is working.

As I am not knowledgeable in this domain, let me ask you for your expertise for this one.
