Question

I was trying something like this:

map $http_referer $setCookie {
        default                "referrer={$http_referer};Domain=.verbalink.com";
        ~*test1\.com           "referrer=bl;Domain=.verbalink.com;Max-Age=31536000";

}

server{
    add_header Set-Cookie $setCookie;
}

But when the cookie is created it has ${http_referer} as the value not the actual http referer. I also tried {$http_referer} and $http_referer but none worked. How can I get the referer into my Cookie?

Answer 1

map $http_referer $setCookie {
    default       $http_referer;
    ~*test1\.com  "bl;Max-Age=31536000";
}

server{
    add_header Set-Cookie "referrer=$setCookie;Domain=.verbalink.com";
}

The resulting value can be a string or another variable. © http://nginx.org/r/map

vs.

value can contain variables © http://nginx.org/r/add_header
