+Caddy is a webserver with automatic HTTPS and modern defaults (e.g. http2, websocket support).
 This article is about Caddy v2.
+Note that caddy does not support <code>.htaccess</code> which is only supported in Apache.
+==Caddyfile==
+===Reverse Proxy===
+Just use the [https://caddyserver.com/docs/caddyfile/directives/reverse_proxy reverse_proxy] directive.
+By default, this will automatically preserve headers.
+Things like websockets will work automatically.
+<pre>
+gitlab.example.com {
+  encode zstd gzip
+  reverse_proxy localhost:8001
+}
+</pre>
+====To HTTPS====
+If you are reverse proxying to another HTTPS, you may need to specify the SNI as follows:
+<pre>
+dev2.davidl.me {
+  reverse_proxy https://192.168.1.41 {
+    transport http {
+      tls_server_name dev2.davidl.me
+    }
+  }
+}
+</pre>
+* Try this if you get <code>502</code> errors.
+===Only Local===
+<pre>
+  @localnet remote_ip 127.0.0.1 192.168.0.0/16
+  @notlocalnet not remote_ip 127.0.0.1 192.168.0.0/16
+</pre>
+==PHP==
+# Install <code>php-fpm</code>
+# Modify <code>/etc/php/7.4/fpm/pool.d/www.conf</code> to listen on a socket or port (e.g. 9000)
+<pre>
+example.com {
+  root * /var/www/wordpress
+  encode zstd gzip
+  php_fastcgi unix//run/php/php-version-fpm.sock
+  file_server
+}
+</pre>
+Notes
+* If you prefer to use a UNIX socket, you can use <code>php_fastcgi unix//var/run/php/php7.4-fpm.sock</code>
+==HTTP3==
+Experimental HTTP3 support can be enabled by adding the following to your Caddyfile.<br>
+Note that HTTP3/QUIC uses UDP which needs to be allowed in your firewall and port forwarded through any NATs.<br>
+<pre>
+{
+  servers {
+    protocol {
+      experimental_http3
+    }
+  }
+}
+</pre>
