Run HTTP and HTTPS Simultaneously on Same Domain

If you need to run HTTP and HTTPS simultaneously on the same domain, create a VirtualHost declaration for example.com:80 and another for example.com:443. The following example is based on a local setup using MAMP, but the idea is the same for a Vagrant box or production machine.

 
<VirtualHost example.org:80>
  ServerName example.org
  ServerAlias www.example.org
  DocumentRoot "/var/www/example/docroot"
  SetEnv APP_ENV "LOCAL"
  ErrorLog /var/www/example/assets/logs/example_error.log
  <Directory /var/www/example/docroot>
    AllowOverride All
  </Directory>
</VirtualHost>

<VirtualHost example.org:443>
  ServerName example.org
  ServerAlias www.example.org
  DocumentRoot "/var/www/example/docroot"
  SetEnv APP_ENV "LOCAL"
  ErrorLog /var/www/example/assets/logs/example_error.log
  <Directory /var/www/example/docroot>
    AllowOverride All
  </Directory>
  SSLEngine on
  SSLCertificateFile /Applications/MAMP/conf/apache/server.crt
  SSLCertificateKeyFile /Applications/MAMP/conf/apache/server.key
</VirtualHost>
