In the admin manual sample nginx configuration
the following headers are set in the server block:
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
add_header X-Robots-Tag none;
add_header X-Download-Options noopen;
add_header X-Permitted-Cross-Domain-Policies none;
add_header Referrer-Policy no-referrer;
and again in this location block:
location ~ \.(?:css|js|woff2?|svg|gif|map)$ {
try_files $uri /index.php$request_uri;
add_header Cache-Control "public, max-age=15778463";
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
add_header X-Robots-Tag none;
add_header X-Download-Options noopen;
add_header X-Permitted-Cross-Domain-Policies none;
add_header Referrer-Policy no-referrer;
Why do we have to set them twice?
And why is there no “always” at the end of each line?
Wouldn’t that be a more secure configuration?
