is primarily intended to allow input for actions to take place
without causing a change to the user agent's active document view,
although any new or updated metainformation SHOULD be applied
to the document currently in the user agent's active view.
The 204 response MUST NOT include a message-body, and thus
is always terminated by the first empty line after the header fields."
