+## Apache httpd
+
+Apache HTTP server can serve as a reverse proxy using [VirtualHosts](https://httpd.apache.org/docs/2.4/vhosts/examples.html). This snippet would be added to the bottom of httpd.conf. Certbot is supported on httpd but is not used in this example

+```<VirtualHost *:443>
+  ServerName budget.example.com
+  SSLProxyCheckPeerName off
+	SSLProxyVerify none
+  SSLEngine on
+  SSLProxyEngine on
+  SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
+  SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
+  ProxyPass / https://127.0.0.1:5006/ # this can be a remote host, or a container IP
+  ProxyPassReverse / https://127.0.0.1:5006/
+</VirtualHost>
