                     17: As part of the HTTP content negotiation, a server must be able to match the
                     18: preferences sent by the client in an HTTP request with the possible set of
                     19: documents that it has avaiable for this URL. For example , it may have an
                     20: English and a Danish version in which case it looks at the
                     21: <CODE>Accept-Language</CODE> header and sees what the client prefers. The
                     22: Library has a simple "Match" algorithm for finding the best as specified
                     23: by the HTTP specification. As the content algorithm is part of the File Interface
                     24: then all file access regardless of whether it is from a server or a client
