====== Setup TSL (HTTPS) For Website ======
Assume we are using Apache 2.4.
  - Go to ./conf
  - In httpd.conf, enable mod_ssl, and ''Include conf/extra/httpd-ssl.conf'' <code>
LoadModule ssl_module modules/mod_ssl.so

# Secure (SSL/TLS) connections
Include conf/extra/httpd-ssl.conf
</code>
  - Open conf/extra/httpd-ssl.conf
  - Listen 443
  - and setup the DocumentRoot and some basic info, log and SSL cert files.<code>
Listen 443
<VirtualHost _default_:443>

Here, we assume our site is www.example.com, and using port 443(default port) for HTTPS. We installed apache on d:\apache24, and the DocumentRoot would be d:/Apache24/htdocs. The cert files can be buy from some cert company or get it free from https://letsencrypt.org/.
