Forcing a / with .htaccess After redirecting a website to https environment I had the difficulty that .php/ was added to the url which resulted in double content. I have been able to get past this mistake but now I need to force a /  on in the end if the url’s does not have that yet.

Example

Domainname.com/example/


and

Domainname.com/example


Are now visible in Google. I want only the one with the /

Current .htaccess is:

DirectoryIndex index.php
ErrorDocument 404 /404.html

RewriteEngine On
### START WWW &amp; HTTPS
# ensure www.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# ensure https
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} off
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

### END WWW &amp; HTTPS
RewriteBase / 
RewriteRule ^([^.?]+[^.?/])$ $1/ [R=301,L]
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^(.*[^/])/?$ /$1.php [QSA,L]

RewriteRule ^index\.php$ / [R=301,L]

#1)externally redirect "/file.php" to "/file"   
RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]
RewriteRule ^ /%1 [NC,L,R]
#2)Internally map "/file" back to "/file.php"
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ /$1.php [NC,L]
I don't think this is particularly Craft CMS specific problem. Just Apache .htaccess rules in general. I would try to search for and answer of Stack Overflow. I have a strong feeling it's been answered there already.
