Cookie not created until refresh?

I have the following nginx conf file (shortened for the purose of this
question) that is creating a cookie:

map $http_referer $setCookie {
        default "";
        ~*somewebsite\.com

“referrer=bl;Domain=.mysite.com;Max-Age=31536000”;
}

server{

    listen 80;

    server_name mysite.com www.mysite.com dev.mysite.com;

    root /var/www/mysite.com;

    access_log /var/log/nginx/mysite.com.log spiegle;


    add_header Set-Cookie $setCookie;

    location  /{
                #add_header Set-Cookie $setCookie;
    }
}

The issue is that if I click on a link on somewebsite.com it navigates
to
mysite, but does not create the cookie. If I then refresh the page it
will
create the cookie. Why do I have to refresh to have the cookie created
and
how can I get around this?
