How to add CORS headers to several locations in nginx?

Question

I have been able to add a basic CORS support to my nginx server using the code provided in enable-cors.org. However this solution implies to copy and paste that code in every location block, and I have several locations like the following:

location /game1 {
    alias   /development/games/game1/output;
    index  index.html;
}

location /game2 {
    alias   /development/games/game2/output;
    index  index.html;
}

Is there a way to create a rule that includes add_header outside the location blocks?

Edit to clarify: I've tried the following

server {
    listen       80;
    server_name  localhost;

    charset UTF-8;

    #access_log  logs/host.access.log  main;

    if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Origin' '*';
        ...
    }
    location /game1 {
        alias /development/games/game1/output;
    }
    ...
}

But it does not work:

2015/10/14 19:00:01 [emerg] 3464#7384: "add_header" directive is not allowed
here in C:\development\servers\nginx-1.7.9/conf/nginx.conf:43

@hjpotter92 That's the way it is working now, but doing C&P of the same 12 lines in every location seems... wrong — Pablo Lozano, Oct 15 '15 at 08:33

Sure, you can add add_header under the server block, but then it will always be sent, which might not be what you want.

Otherwise, you can create a file with the directives you want, and then include it from each location where you want the CORS headers added.

I had tried to put it under `server`, but I got an error... I will try the `include`approach, copying one line is clean enough for me – Pablo Lozano Oct 15 '15 at 08:39
