Domains

The framework supports virtual hosts — multiple domains on a single server. Use exact names, wildcards, or regular expressions.

"servers": {
    "s1": {
        "domains": [
            "example1.com",
            "*.example1.com",
            "(a1|a2|a3).example1.com",
            "(.1|.*|a3).example1.com"
        ],
        ...
    },
    ...
}

The search is performed by the value of the Host HTTP header. If the header is empty or missing, the client will receive a 404 Not found response.

Wildcard names

A wildcard name can only contain an asterisk at the beginning or end of the name, and only on a period boundary.

The names www.+.example.org and w*.example.org are invalid. However, these names can be specified using regular expressions, such as www(.+).example.org and ^w(.*).example.org$. An asterisk can match multiple parts of a name. The name *.example.org matches not only www.example.org but also www.sub.example.org.

Regular expression names

The regular expressions used by C Web Framework are compatible with the expressions used in the Perl Programming Language (PCRE). For example, ^www\d+\.example\.net$.
