Nginx reverse proxy with rate limiting

ratelimit.nginxconf

upstream myapp {
    server 127.0.0.1:8081;
}

limit_req_zone $binary_remote_addr zone=login:10m rate=1r/s;

server {
    listen 443 ssl spdy;
    server_name _;
  
    ssl on;
    ssl_certificate /etc/nginx/ssl/cert.pem;
    ssl_certificate_key /etc/nginx/ssl/cert.key;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers AES256+EECDH:AES256+EDH;
    ssl_session_cache  builtin:1000  shared:SSL:5m;
    ssl_prefer_server_ciphers on;

  
    location / {
        proxy_pass http://myapp;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
    }
    
    location /account/login/ {
        # apply rate limiting
        limit_req zone=login burst=5;
    
        # boilerplate copied from location /
        proxy_pass http://myapp;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
    }
}

Is is possible to move all proxy_set_header to server block to avoid copy-pasting ? Something like:

server {
    listen 443 ssl spdy;
    server_name _;

    ssl on;
    ssl_certificate /etc/nginx/ssl/cert.pem;
    ssl_certificate_key /etc/nginx/ssl/cert.key;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers AES256+EECDH:AES256+EDH;
    ssl_session_cache  builtin:1000  shared:SSL:5m;
    ssl_prefer_server_ciphers on;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;

    location / {
        proxy_pass http://myapp;
    }

    location /account/login/ {
        # apply rate limiting
        limit_req zone=login burst=5;

        # boilerplate copied from location /
        proxy_pass http://myapp;
    }
}

In a website with high traffic, the configurations must be something like:

limit_req_zone $binary_remote_addr zone=myzone:10m rate=10r/s; or limit_req_zone $binary_remote_addr zone=myzone:50m rate=100r/s; as I understood.

@esaral, Correct 10000 TPS this need to be higher value. Also this depend on server configuration and core availability.

limit_req_zone depends on remote ip? I am guessing if there is only one IP is involved then just 2r/s is fine.

yes, it helps to prevent DOS attack from single IP. No matter how much traffic is you are getting from different IPs /users.
