Single part ranges $ curl -i -H "Range: bytes=0-1023" This value is optional and, if omitted, the end of the document is taken as the end of the range.Īfter understanding the Range syntax, let’s take a few examples: : An integer in the given unit indicating the end of the requested range.: An integer in the given unit indicating the beginning of the request range.

: The unit in which ranges are specified.Range Syntax Range: =- Range: =- Range: =-, - Range: =-, -,. The server is allowed to ignore the Range header and return the entire file with a status code of 200. If the requested range is not valid, the server will return a 416 Range Not Satisfiable status code, indicating a client error. If the server returns a range response, the 206 Partial Content status code is required. Within a Range header, multiple parts can be requested at once, and the server will return them as a multipart file. If the Accept-Ranges header is present in the response (and its value is not “none”), then the server supports range requests.

Range requests are useful when transferring large media files, or in conjunction with the resume file download feature. HTTP range requests allow the server to send only part of the HTTP message to the client. Next, let’s start with HTTP range requests. After looking at the above figure I believe you have a certain understanding of the solution for large file downloads.
