Range

The Range request HTTP header indicates the part of a document that the server should returns to the requests. Several parts can be requested with one Range header, and the server may send back these ranges in a multipart document. If the server send back ranges, it uses the 206 Partial Content for the response; If the ranges are invalid, the server returns the 416 Range Not Satisfiable error. The server can ignore the Range header and returns the whole document, with the 200 status code.
