The Range header is used in requests for parts or ranges of an entity. Its value indicates the range of the entity that is included in the message.

Requests for ranges of a document allow for more efficient requests of large objects (by requesting them in segments) or for recovery from failed transfers (allowing a client to request the range of the resource that did not make it). Range requests and the headers that make the requests possible are discussed in detail in Chapter 15.
