AcceptRanges is a string property used to represent the value for the HTTP Accept-Ranges header from an HTTP response. AcceptRanges indicates that the HTTP server acceptance of range requests for a resource. 

AcceptRanges can contain the values 'bytes' or 'none' in the range unit. An HTTP client can generate a byte-range requests without having received the AcceptRange header for the resource involved. 

Servers that do not accept any kind of range request for a resource may send the value 'none' in the AcceptRanges property to advise the client not to attempt a range request.
