示例1: net_IsValidHostName

    // willing to send to lower-level DNS logic. This is more
    // self-documenting, and can also be slightly faster than the
    // blacklist approach, since DNS names are the common case, and
    // the commonest characters will tend to be near the start of
    // the list.

    // Whitelist for DNS names (RFC 1035) with extra characters added 
    // for pragmatic reasons "$+_"
    // see https://bugzilla.mozilla.org/show_bug.cgi?id=355181#c2
