Add_headers on text/html only?

Server NGINX
1

I’m trying to add three headers for security to all text/html content:

add_header X-Content-Type-Options ‘nosniff’;
add_header X-Frame-Options ‘DENY’;
add_header X-XSS-Protection ‘1; mode=block’;

I’d like to add these to a number of different sites & virtual hosts in
nginx.

Q: Is there an easy way to add this to multiple different hosts
without updating every server{} block?

Can I put this into an http{} section in some way (but still limit it
to text/html)?

Best,
Nick

add_header will not add header with empty value, so

add_header X-test $test;
map $sent_http_content_type $test {
    text/html  1;
}

should work.
