Response class for
Already Reported (WebDAV) responses (status code 208).
Already Reported (WebDAV) response indicates that the server has received the request, and that the members of a DAV binding have already been enumerated in a preceding part of the (multi-status) response, and are not being included again.
This class also includes (indirectly) module
Net::HTTPHeader, which gives access to its methods for getting headers.
