Explains how to install and configure Apache with a mod_md module to secure traffic with Let's Encrypt free TLS/SSL certificate on Ubuntu 20.04 LTS Linux.

You want to force people coming to your site to use HTTPS. Either for the entire site or a small sub-section of it.

RewriteEngine On
# This will enable the Rewrite capabilities

RewriteCond %{HTTPS} !=on
# This checks to make sure the connection is not already HTTPS

RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
# This rule will redirect users from their original location, to the same location but using HTTPS.
# i.e.  http://www.example.com/foo/ to https://www.example.com/foo/
# The leading slash is made optional so that this will work either in httpd.conf
# or .htaccess context

Automatically enable HTTPS on your website with EFF's Certbot, deploying Let's Encrypt certificates.

The web is (in 2015) a place where security is increasing essential, and always under threat. It is also a space which needs to be consistent, logical, and user-serving. There follow some thoughts following many recent discussions of "HTTPS Everywhere" and points west.
