.htaccess Adding HTTPS forcing to existing rewrite rules of subdirectory - apache

Question

Probably I'm overseeing something very basic, htaccess is not my field of expertise.
My site is https-only, to achieve this, the root folder / contains these lines:
RewriteEngine On
RewriteCond %{ENV:HTTPS} !on
RewriteRule ^(.*) https://%{HTTP_HOST}/$1 [R=301,L]
This works just fine. Now we have a new folder called /projects, which contains its own htaccess rules to translate the url in a database query by a file called /projects/project.html
The working htaccess within the folder /projects is:
RewriteEngine On
RewriteBase /projects/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ project.html?project=$1 [QSA,L]
Now I would like to force https connection on this one, because the https rule in the main directory is not applied on /projects if you visit by http://URL directly. Therefore I modified the file to:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://example.com%{REQUEST_URI} [R=301,L,NE]
RewriteBase /projects/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ project.html?project=$1 [QSA,L]
With this, it switches to https, but I keep getting "ERR_TOO_MANY_REDIRECTS".
When I change the lines as #thickguru suggested, like this:
RewriteRule ^(.*)$ https://example.com/$1 [R,L]
It will redirect me to https://example.com/index.html right away.
I fiddled around with the settings, also with the information of this post, however still I can't get it to work.

Answer 1

I just noticed it the variable you are matching against is %{ENV:HTTPS} , so , you can use the following rule in /projects/.htaccess :
RewriteEngine on
RewriteCond %{ENV:HTTPS} !on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [NE,L,R]
Clear your browser cache or try a diffrent browser to test this.

Answer 2

Use this in your .htaccess:
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://www.example.com%{REQUEST_URI} [R=301,L,NE]
Also, place this above your your other RewriteRule, so that your .htaccess will look like:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^.*$ https://www.example.com%{REQUEST_URI} [R=301,L,NE]
RewriteBase /projecten/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ project.html?project=$1 [QSA,L]
EDIT - Try this:
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]
