* according to RFC 3454, i.e. the same encoding returned by nsIURI::GetAsciiHost().
* If consumers wish to compare the result of this method against the host from
* another nsIURI, the host should be obtained using nsIURI::GetAsciiHost().
* In the case of nested URIs, the innermost URI will be used.
