Adding "Link" Header

Server NGINX
1

To avoid SEO issues on my subdomains, I need to add a “Link” header to
support Google’s canonical header. The format is as follows (from
Official Google Webmaster Central Blog: Supporting rel="canonical" HTTP Headers):

Link: http://www.example.com/white-paper.html; rel=“canonical”

So, the add_header command would need to reference $uri, but it also
needs a semi-colon and double quotes. How can I add this header to my
config?

add_header Link “<$scheme://$http_host$request_uri>; rel="canonical"”;

location ~* ^/(.*)(.pdf)$ {
add_header Link “<$scheme://$host:$server_port/$1.html>;
rel="canonical"”;
}

You can use $http_host instead of $host:$server_port, but if you get
a request without the Host header, $http_host will be empty.
