 ===== Using Apache to reverse proxy Tomcat =====
+Install and setup Apache with certbot SSL certificates. Then in the le-ssl.conf file (eg /etc/httpd/sites-enabled/000-defualt-le-ssl.conf) add teh following into the <VirtualHost *:443> node:
+       ProxyPass /greenstone3 http://localhost:8383/greenstone3
+       ProxyPassReverse /greenstone3 http://localhost:8383/greenstone3
+       <Location /greenstone3>
+            ProxyPassReverseCookiePath /greenstone3 /greenstone3
+       </Location>
+       ProxyPass /webswing-server/ http://localhost:8383/webswing-server/ upgrade=websocket
+In build.properties, you will need to set the revproxy settings:
+    revproxy.protocol=https
+    revproxy.domain=<DOMAIN>
+    ##revproxy.opt_port=8080  - this can stay commented out if you don't want a port number to appear in the public URL
+    ##revproxy.context=/greenstone3  - this can stay commented out if you are using the same context as greenstone3.context

 To have your webserver running under https, you need an SSL certificate. Many hosting platforms have tools to let you use HTTPS. See [[https://certbot.eff.org/hosting_providers]] to check your hosting provider.

 Take note of the "What you need" section. Then, choose your webserver ('apache' or 'other' for Tomcat) and operating system, and it will give you instructions to install certbot, plus also instructions to run it to get certificates.

 There is a script in Greenstone3 - ''ant-update-https-cert-and-restart.sh'' - which does these things. You can add this script as a deploy-hook. To get this added to the renewal options, run a forced renewal.
