Remarks

The utility method to check whether a host name is in a domain or not.

This concept is described in the cookie specification. To understand the concept, some terminologies need to be defined first: <blockquote> effective host name = hostname if host name contains dot<br>                   or = hostname.local if not </blockquote>

Host A's name domain-matches host B's if: <blockquote><ul> <li>their host name strings string-compare equal; or</li> <li>A is a HDN string and has the form NB, where N is a non-empty name string, B has the form .B', and B' is a HDN string. (So, x.y.com domain-matches .Y.com but not Y.com.)</li> </ul></blockquote>

A host isn't in a domain (RFC 2965 sec. 3.3.2) if: <blockquote><ul> <li>The value for the Domain attribute contains no embedded dots, and the value is not .local.</li> <li>The effective host name that derives from the request-host does not domain-match the Domain attribute.</li> <li>The request-host is a HDN (not IP address) and has the form HD, where D is the value of the Domain attribute, and H is a string that contains one or more dots.</li> </ul></blockquote>

Examples: <blockquote><ul> <li>A Set-Cookie2 from request-host y.x.foo.com for Domain=.foo.com would be rejected, because H is y.x and contains a dot.</li> <li>A Set-Cookie2 from request-host x.foo.com for Domain=.foo.com would be accepted.</li> <li>A Set-Cookie2 with Domain=.com or Domain=.com., will always be rejected, because there is no embedded dot.</li> <li>A Set-Cookie2 from request-host example for Domain=.local will be accepted, because the effective host name for the request- host is example.local, and example.local domain-matches .local.</li> </ul></blockquote>
