Apache HTTP Server

VirtualHost

A basic virtualhost looks like this

<VirtualHost *:80>
  ServerName my_server.com
  ServerSignature Off
  DocumentRoot "/www/example2"
</VirtualHost>

Compression

Redirects

Universal Redirect

RedirectMatch ^(.*)$ https://davidl.me/

HTTPS Redirect

<VirtualHost *:80>
  ServerName my_server.com
  ServerSignature Off

  RewriteEngine on
  RewriteCond %{HTTPS} !=on
  RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [NE,R,L]
  RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

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.

Requirements

mod_proxy
mod_proxy_wstunnel for websockets

  RewriteEngine on
  RewriteCond %{HTTP:Upgrade} =websocket
  RewriteRule /(.*)     ws://192.168.1.99/$1  [P,L]
  RewriteCond %{HTTP:Upgrade} !=websocket
  RewriteRule /(.*)     http://192.168.1.40:99/$1 [P,L]
  ProxyPreserveHost On
  ProxyRequests Off
  ProxyPass / http://192.168.1.99:80/
  ProxyPassReverse / http://192.168.1.99:80/

  # Proxy websockets

  ProxyPass "/wss2/" "wss://echo.websocket.org/"

.htaccess

.htaccess allows modifying selected Apache configurations on a per-folder basis.
To enable this feature, add AllowOverride All to your apache.conf for the directories you want to allow .htaccess files.
