Server {listen 80 default_server; server_name _; return 501;} 2) Jump to the home page server {listen 80 default_server; server_name _; rewrite ^ (. *) http://www.jb51.com/$1 permanent;} 3) all requests for www.jb51.com are redirected to the following domain name www.yisu.com. (need to be put into server configuration) if ($host ~'^ www.jb51.com') {return 301 https://www.yisu.com$request_uri;} 4) Nginx restricts malicious resolution of illegal domain names to local servers and IP access website server {undefined listen 80 default_server; server_name _; return 501;} this is the end of the content on "how Nginx prohibits ip access or illegal domain name access".
