Correct usage of proxy_set_header?

Server NGINX
1

Hello all!
I have configured a location that acts list a transparent proxying
cache:

    location /get
    {
        set $hostx "";
        set $addrs "";
        if ( $uri ~ "^/get/http./+([^/]+)/(.+)$") {
            set $hostx $1;
            set $addrs $2;
        }
        resolver 8.8.8.8;
        proxy_set_header Referer " ";
        proxy_pass http://$hostx/$addrs;
        proxy_redirect off;
        access_log /var/log/nginx/get_access.log;
    }

Basically when i browser to:

http://mysite.com/get/http://foo.com/bar/some.html

it’ll get:
http://foo.com/bar/some.html

The code indeed works that way, except that the directive
proxy_set_header referer " " is ignored. No matter what value I supply there (in the
code
above, empty), my get_access.log will always show the referer being the
original refering page?

What was wrong in my config?
Thanks,

The proxy_set_header directive controls headers sent to a proxied
server. It has nothing to do with what’s logged to access log on
your server. Try looking into logs of the proxied server instead.
