depends on google
, so google_scholar

google_scholar on;
}

, the robots.txt
will be replaced with the version of google itself. #...

google_robots_allow on;

#...
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.
#
## eg.
## i want to proxy the domain 'www.google.com' like this
## vps(hk) -> vps(us) -> google
#
#
## configuration of vps(hk)
#
server {
# ...
location / {
google on;
google_ssl_off "www.google.com";
}
# ...
}
upstream www.google.com {
server < ip of vps(us) >:80;
}
#
## configuration of vps(us)
#
server {
listen 80;
server_name www.google.com;
# ...
location / {
proxy_pass https://www.google.com;
}
# ...
}
