Apache HTTP Server
VirtualHost
A basic virtualhost looks like this
<VirtualHost *:80> ServerName my_server.com ServerSignature Off DocumentRoot "/www/example2" </VirtualHost>
Full VirtualHost
The following virtual host has an HTTPS redirect and uses an LetsEncrypt ssl certificate
# contents of /etc/apache2/sites-available/davidl.me <VirtualHost *:80> ServerName www.davidl.me ServerAlias davidl.me ServerSignature Off RewriteEngine on RewriteCond %{SERVER_NAME} =www.davidl.me [OR] RewriteCond %{SERVER_NAME} =davidl.me RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost> <IfModule mod_ssl.c> <VirtualHost *:443> ServerName www.davidl.me ServerAlias davidl.me ServerSignature Off ServerAdmin webmaster@localhost DocumentRoot /var/www/davidl_me/public ErrorLog ${APACHE_LOG_DIR}/davidlme_error.log CustomLog ${APACHE_LOG_DIR}/davidlme_access.log combined Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/www.davidl.me/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/www.davidl.me/privkey.pem </VirtualHost> </IfModule> <Directory /var/www/davidl_me/public> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>

Proxying
mod_proxy documentation
mod_proxy_wstunnel documentation
General proxying to another server.
Note that this can be another service on the same machine (localhost), same network, or another network entirely.
This can be useful if you have a some entry point which handles HTTPS for another service on the same PC which does not handle HTTPS.
