Server names

Server names

• Wildcard names
• Regular expressions names
• Miscellaneous names
• Optimization
• Compatibility

Server names are defined using the server_name directive and determine which server block is used for a given request. See also “How nginx processes a request”. They may be defined using exact names, wildcard names, or regular expressions:

server {
    listen       80;
    server_name  example.org  www.example.org;
    ...
}

server {
    listen       80;
    server_name  *.example.org;
    ...
}

server {
    listen       80;
    server_name  mail.*;
    ...
}

server {
    listen       80;
    server_name  ~^(?<user>.+)\.example\.net$;
    ...
}

When searching for a virtual server by name, if name matches more than one of the specified variants, e.g. both wildcard name and regular expression match, the first matching variant will be chosen, in the following order of precedence:

1. exact name
2. longest wildcard name starting with an asterisk, e.g. “*.example.org”
3. longest wildcard name ending with an asterisk, e.g. “mail.*”
4. first matching regular expression (in order of appearance in a configuration file)
