Use .htaccess to redirect HTTP to HTTPs

Question

Please, don't recommend me the long and very detailed thread with more than 173 upvotes. It didn't work for me. I have also tried many others (1, 2, 3, 4). They all give me TOO_MANY_REDIRECTS or error 500. So, here is my issue:

With my current .htaccess, this is what happens:

https://www.dukescasino.com/ - works perfectly

https://dukescasino.com/ - redirects to the above which is great

The two options below loads fine, but it should be redirecting to the https version:

http://www.dukescasino.com/

http://dukescasino.com/

Here is the current .htaccess:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

I don't believe it is relevant, but if so, here is the list of current active plugins:

• Advanced Custom Fields
• All In One SEO Pack
• Bop Search Box Item Type For Nav Menus
• Contact Form 7
• Disable Comments
• Google XML Sitemaps
• Jetpack by WordPress.com
• Search & Filter
• Slider WD
• TablePress
• UpdraftPlus - Backup/Restore
• Wordfence Security
• WPide
• WP Smush
• WP Super Cache

Test A:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{HTTPS} off # First rewrite to HTTPS: # Don't put www. here. If it is already there it will be included, if not # the subsequent rule will catch it. RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] # Now, rewrite any request to the wrong domain to use www. RewriteCond %{HTTP_HOST} !^www\. RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Result: ERR_TOO_MANY_REDIRECTS

Test B:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{HTTPS} !=on RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Result: ERR_TOO_MANY_REDIRECTS

Test C:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{SERVER_PORT} ^80$  RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Result: ERR_TOO_MANY_REDIRECTS

Test D:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Result: ERR_TOO_MANY_REDIRECTS

Test E:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI}$1 [R=301,L] RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI}$1  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Result: 302 found. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

On Dreamhost, this worked:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{HTTPS} !=on RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

Answer 2

Problem solved!

Final .htaccess:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase /  RewriteCond %{ENV:HTTPS} !=on RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]  # BEGIN WordPress RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule>
