Using nginx 1.2.1 I am able to add multiple headers using add_header as follows:

server {
    listen       80;
    server_name  localhost;
    root /var/www;
    add_header Name1 Value1;      <=== HERE
    add_header Name2 Value2;      <=== HERE

    location / {
        echo "Nginx localhost site";
    }
}

GET /
HTTP/1.1 200 OK
Name1: Value1
Name2: Value2

However I soon as I use the add_header directive inside location, the other add_header directives under server are ignored

server {
    listen       80;
    server_name  localhost;
    root /var/www;
    add_header Name1 Value1;      <=== HERE
    add_header Name2 Value2;      <=== HERE

    location / {
        add_header Name3 Value3;  <=== HERE
        add_header Name4 Value4;  <=== HERE
        echo "Nginx localhost site";
    }
}

GET /
HTTP/1.1 200 OK
Name3: Value3
Name4: Value4

The documentation says that both server and location are valid context and doesn't state that using add_header in one prevents using it in the other.

Q1: Do you know if this is a bug or the intended behaviour and why?

Q2: Do you see other options to get this fixed than using the HttpHeadersMoreModule module?
