Description
Using http2_push directive in location block doesn't push resources. Using Link header (via add_header directive or supplied by backend) makes the browser issue a GET (preload) request, which is not the same.
Configuration file:
listen 127.0.0.1:80 http2;
server_name example.com;
root /var/www;
index index.php index.html;
error_page 404 = @notfound;
http2_push_preload on;
location = /manifest.json {
expires 30d;
http2_push /logos/logo.png;
add_header Link "</logos/logo-2x.png>; rel=preload; as=image";
}
(There are many more location blocks, some with regex, some with prefix matching. Except those, there are no other directives in server{} block.)
http{} block has these, plus all the "standard" stuff.
sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 120; types_hash_max_size 2048; server_tokens off; server_names_hash_bucket_size 64; server_name_in_redirect off;
