Upstreaming
upstream can help you to avoid name resolving cost, decrease the possibility of google robot detection and proxy through some specific servers.
upstream www.google.com {
server 173.194.38.1:443;
server 173.194.38.2:443;
server 173.194.38.3:443;
server 173.194.38.4:443;
}
Proxy Protocol
By default, the proxy will use https to communicate with backend servers.
You can use google_ssl_off to force some domains to fall back to http protocol.
It is useful, if you want to proxy some domains through another gateway without ssl certificate.
