The HyperText Transfer Protocol (HTTP) 416 Range Not Satisfiable error response code indicates that a server cannot serve the requested ranges. The most likely reason is that the document doesn't contain such ranges, or that the {{HTTPHeader("Range")}} header value, though syntactically correct, doesn't make sense.

The 416 response message contains a {{HTTPHeader("Content-Range")}} indicating an unsatisfied range (that is a '*') followed by a '/' and the current length of the resource. E.g. Content-Range: bytes */12777

Faced with this error, browsers usually either abort the operation (for example, a download will be considered as non-resumable) or ask for the whole document again.
