The RangeHeaderValue class provides support for a byte range in a Range header as defined in RFC 2616 by the IETF.

A Range header can specify multiple byte ranges.

An example of a byte-range in a Range header in an HTTP protocol request that requests the first 100 bytes would be would be the following:

Range: bytes=0-99\r\n\r\n

A HTTP server indicates support for Range headers with the Accept-Ranges header. An example of the Accept-Ranges header from a server that supports byte-ranges would be as follows:

Accept-Ranges: bytes\r\n\r\n

If an Accept-Ranges header is not received in the header of the response from the server, then the server does not support Range headers. An example of the Accept-Ranges header from a server that does not support ranges, but recognizes the Accept-Ranges header, would be as follows:

Accept-Ranges: none\r\n\r\n
