##
# Friendica Nginx configuration template to be autoconfigured with certbot
# based on sample-nginx.config by Olaf Conradi
#
# On Debian based distributions you can add this file to
# /etc/nginx/sites-available
#
# Then customize it to your needs. At least replace the server_name in line 41.
#
# Enable the configuration by
# symlink it to /etc/nginx/sites-enabled
#
# and run
# certbot --nginx -d friendica.example.net
#
# Then reload Nginx using
# systemctl nginx reload
#
##

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
#
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
##

##
# This configuration assumes your domain is example.net
# You have a separate subdomain friendica.example.net
# You want all Friendica traffic to be https using letsencrypt with certbot
# You have an SSL certificate and key for your subdomain
# You have PHP FastCGI Process Manager (php7.4-fpm) running on localhost
# You have Friendica installed in /var/www/friendica

# if X-Request-ID is set, NGINX will forward the same value to the next upstream
# if the header is not set, NGINX will generate a random request identifier and add it to the request.
#
# To guarantee backward compatibility, map to format the $request_id variable to a format that matches any old setups.
