How to force HTTPS using the .htaccess file

To force all web traffic to use HTTPS insert the following lines of code in the .htaccess file in your website’s root folder. 

Important:If you have existing code in your .htaccess, add this above where there are already rules with a similar starting 
prefix.

# Redirect to SSL version of a site without needing to set the domain name,
  RewriteCond %{HTTPS} off
  RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

# Redirect to SSL version of site. Be sure to set your actual domain name.
RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]
Be sure to replace www.example.com with your actual domain name.

To force a specific domain to use HTTPS, use the following lines of code in the .htaccess file in your website's root folder:

RewriteEngine On 
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]

Make sure to replace example\.com with the domain name you're trying force to https. Additionally, you need to replace 
www.example.com with your actual domain name.

If you want to force SSL on a specific folder you can insert the code below into a .htaccess file placed in that specific 
folder:

RewriteEngine On 
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{REQUEST_URI} folder 
RewriteRule ^(.*)$ https://www.example.com/folder/$1 [R,L]

Make sure you change the folder reference to the actual folder name. Then be sure to replace www.example.com/folder with your 
actual domain name and folder you want to force the SSL on.
