Forum: NGINX 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?
