Sharing is caring!

Duplicate content problem caused by multiple redirections
If SSL is installed on your webserver and has not created any rewrite rules, all of these pages probably return a valid 200 page.

The best solution is

#### Forcefully add HTTPS://WWW and remove trailing slash (/) from files ####
## On rewrite engine
RewriteEngine on

# Remove trailing slash from non-filepath urls
RewriteCond %{REQUEST_URI} /(.+)/$
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ https://www.domian.com/%1 [R=301,L]

# Include trailing slash on directory 
RewriteCond %{REQUEST_URI} !(.+)/$
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.+)$ https://www.domian.com/$1/ [R=301,L]

# Forcefully add HTTPS and WWW 
RewriteCond %{HTTP_HOST} !^www\.(.*)$ [OR,NC]
RewriteCond %{https} off  
RewriteRule ^(.*)$ https://www.domian.com/$1 [R=301,L]
