Hi @Guglielmo89 ,
Rules seems good however can you give try by making it to uppercase like below
RewriteCond %{REQUEST_URI} ^/?$
RewriteCond %{HTTP:X-AEM-CLIENT-COUNTRY} ^US$
RewriteRule ^/?$ /content/${CONTENT_FOLDER_NAME}/us/en/home.html [PT,L]
and header in lowercase
/headers {
"Cache-Control"
"Content-Disposition"
"Content-Type"
"Expires"
"Last-Modified"
"X-Content-Type-Options"
"x-aem-client-country"
"x-aem-client-continent"
}
Also, under my.vhost, added Vary header to invalidate cache when country header changes if required
<VirtualHost *:80>
<Directory>
Header set Vary "x-aem-client-country"
</Directory>
Thanks
