Question: how to hide header "Server"

[Toshiki NISHIHATA]

Hello,

I use nginx of GNU/Linux Ecth(testing) package.

# nginx  -v
nginx version: nginx/0.4.2
built by gcc 4.1.2 20060901 (prerelease) (Debian 4.1.1-13)

For security, I want to hide the http header; "Server: nginx/0.4.2
".
I thouth that "proxy_pass_header Server" allows transferring "Server"
header forbidden.
So, I rewrite follow at /etc/nginx/nginx.conf, but header "Server" didn't hide.


location / {
     root   /var/www;
     proxy_pass_header  Server;
}

$ telnet sample.com 80
GET /index.html HTTP/1.0

HTTP/1.1 200 OK
Server: nginx/0.4.2              <--------------   want to hide!!
