Too many redirects configuring HTTPS redirect on .htaccess

Question

I have a website with https://example.com , http://example.com , https://www.example.com and https://www.example.com working fine.

Now I want that regardless of which one you type, it redirects to https://www.example.com . I am using the code below in my .htaccess (and tried many more), but after doing the redirection in the browser the page doesn't load, giving error "Too many redirects". I tried of course deleting cache.

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

Answer 1

Since my hosting is Heroku, which has special rules, any of the other solutions didn't work for me. The following code in .htaccess worked like a charm:

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
