Slightly tighter CORS config for nginx

# A modification of https://gist.github.com/1064640/ to include a white-list of URLs
#
# Despite the W3C guidance suggesting that a list of origins can be passed as part of
# Access-Control-Allow-Origin headers, several browsers (well, at least Firefox)

# method to control access instead.

# NB: This relies on the use of the 'Origin' HTTP Header.

For me something like this broke my preflight check for cors and therefor failing cors for some reason...

` gzip off;
proxy_set_header X-Forwarded-Ssl on;
client_max_body_size 50M;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Frame-Options SAMEORIGIN;
proxy_pass http://test.app_backend;

  set $cors "";

  if ($http_origin ~* (.*\.test.app|https://waves.exchange|.*\.test2.app|.*\.wallet.com)) {
    set $cors "true";
  }
  if ($cors = "true") {
  add_header 'Access-Control-Allow-Origin' "$http_origin" always;
  add_header 'Access-Control-Allow-Credentials' 'true' always;
  add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE' always;
  add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,signature,timestamp' always;
  add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range' always;
  }
  if ($request_method = 'OPTIONS') {
    return 204;
  }
