htaccess - HTTP to HTTPS and .HTML to / - .htaccess

Question

I need help with an .htaccess that:
forces http:// to https://
AND
forces .html to /
What I have so far:
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.html [NC,L]

Answer 1

Options -MultiViews
RewriteEngine On
#1 This line checks if the https is off
RewriteCond %{HTTPS} ^off$
#then, redirect to https
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [NC,L,R]
#2 this line checks if the request is /file.html
RewriteCond %{THE_REQUEST} /([^.]+)\.html [NC]
#then redirect /file.html to /file
RewriteRule ^ /%1 [NC,L,R]
#3 if the request is not for dir
RewriteCond %{REQUEST_FILENAME} !-d
#and the request is an existing filename
RewriteCond %{REQUEST_FILENAME}.html -f
#then rewrite /file to /file.html
RewriteRule ^([^/]+)/?$ $1.html [NC,L]
In the example above, the first condition is met when the original scheme is HTTP, and then the rule is processed. HTTP goes to HTTPS. The first Round of rewrite processing ends here.
In the second round, mod_rewrite accepts the URI /file.html and the rule redirects it to /file, since the /file does not exist in directory, so we need to rewrite it to the original file #3...

Answer 2

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [R,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.html [NC,L]
I've used both of them before, but I haven't used them together. Hope this helps.
(EDIT)
To actually FORCE extensions to look like directories:
RewriteBase /
RewriteCond %{THE_REQUEST} \s/+(.+?)\.html[\s?] [NC]
RewriteRule ^ /%1/ [R=302,L,NE]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=302,NE,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1\.html -f [NC]
RewriteRule ^(.+?)/?$ $1.html [L]

Answer 3

First of all, make sure mod-rewrite is enabled.
Then, put this code in your htaccess (which should be in document root folder)
Options -MultiViews
RewriteEngine On
RewriteBase /
# Redirect http urls to https equivalent
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://{HTTP_HOST}/$1 [R=301,L]
# Redirect existing /path/file.html to /path/file/
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{THE_REQUEST} \s/(.+?)\.html\s [NC]
RewriteRule ^ %1/ [R=301,L]
# Internally rewrite back /path/file/ to /path/file.html (if existing)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}/$1\.html -f
RewriteRule ^(.+)/$ $1.html [L]
Warning:
Make sure to serve the same document root as http for https (apache ssl block configuration)
Be aware that this creates virtual directories (by adding a trailing
slash) which could mess up your html resources (if you're using
relative paths instead of absolute paths). If so, use absolute paths
instead
