WordPress doesn't respect nginx headers - php

Question

I host some websites on my VPS, some "static" and some dynamic (WordPress). The static websites (static PHP pages) "respect" the headers I set in nginx conf, http section. Example:
add_header Strict-Transport-Security "max-age=31536000; includeSubdomains;";
add_header X-Cache $upstream_cache_status;
Header:
HTTP/1.1 200 OK
Server: nginx
Date: Tue, 16 Sep 2014 17:09:04 GMT
Content-Type: text/html; charset=utf-8
Transfer-Encoding: chunked
Connection: keep-alive
Vary: Accept-Encoding
X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
X-Cache: HIT
Strict-Transport-Security: max-age=31536000; includeSubdomains;
WordPress websites instead don't have these headers I set:
HTTP/1.1 200 OK
Server: nginx
Date: Tue, 16 Sep 2014 17:08:25 GMT
Content-Type: text/html; charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Vary: Accept-Encoding
X-Pingback: http://website.com/xmlrpc.php
Link: <http://wp.me/P4zIfv-2>; rel=shortlink
X-UA-Compatible: IE=Edge,chrome=1
The two websites have the same vhost config! Of course liste, server_name, index ecc.. and then the locations:
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
fastcgi_cache website.com;
fastcgi_cache_valid 200 20m;
fastcgi_cache_bypass $no_cache;
fastcgi_no_cache $no_cache;
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
include /etc/nginx/fastcgi.conf;
fastcgi_pass unix:/var/run/php5-fpm.sock;
}
Why does this happen with WP?

Answer 1

See: nginx add_header not working
"Second issue was that the location / {} block I had in place was actually sending nginx to the other location ~* (.php)$ block (because it would repath all requests through index.php, and that actually makes nginx process this php block). So, my add_header directives inside the first location directive were useless, and it started working after I put all the directives I needed inside the php location directive."

So put them INSIDE your location block
