.htaccess

#DO NOT COPY\PASTE. Take only what you need carefully.
#The following code is just a few **examples** of optimizations that you can do in .htaccess file.


# HTTPS forced
<IfModule mod_rewrite.c>

    #RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
# END HTTPS

#Remove Facebook fbclid
<IfModule mod_rewrite.c>
RewriteCond %{QUERY_STRING} ^(.*)(?:^|&)fbclid=(?:[^&]*)((?:&|$).*)$ [NC]
RewriteCond %1%2 (^|&)([^&].*|$)
RewriteRule ^(.*) /$1?%2 [R=301,L]
</IfModule>
#END

#RewriteCond %{QUERY_STRING} ^(.*)&?fbclid=[^&]+&?(.*)$ [NC]
#RewriteRule ^(.*)$ /$1?%1%2 [R=302,L]
