Only serve requests to a specific domain?
When you setup Nginx, set your "server block" to be specific rather than general. This one would only pick up traffic going to www.domain1.com.
http {
index index.html;
server {
server_name www.domain1.com;
access_log logs/domain1.access.log main;
root /var/www/domain1.com/htdocs;
}
}
Where as this one would pick up all traffic to port 80.
http {
index index.html;
server {
listen 80 default_server;
server_name _; # This is just an invalid value which will never trigger on a real hostname.
access_log logs/default.access.log main;
server_name_in_redirect off;
root /var/www/default/htdocs;
}
}
