1 Long: range 2 Short: r 3 Help: Retrieve only the bytes within RANGE 4 Arg: <range> 5 Protocols: HTTP FTP SFTP FILE 6 --- 7 Retrieve a byte range (i.e. a partial document) from an HTTP/1.1, FTP or SFTP 8 server or a local FILE. Ranges can be specified in a number of ways. 9 .RS 10 .TP 10 11 .B 0-499 12 specifies the first 500 bytes 13 .TP 14 .B 500-999 15 specifies the second 500 bytes 16 .TP 17 .B -500 18 specifies the last 500 bytes 19 .TP 20 .B 9500- 21 specifies the bytes from offset 9500 and forward 22 .TP 23 .B 0-0,-1 24 specifies the first and last byte only(*)(HTTP) 25 .TP 26 .B 100-199,500-599 27 specifies two separate 100-byte ranges(*) (HTTP) 28 .RE 29 .IP 30 (*) = NOTE that this will cause the server to reply with a multipart 31 response! 32 33 Only digit characters (0-9) are valid in the 'start' and 'stop' fields of the 34 \&'start-stop' range syntax. If a non-digit character is given in the range, 35 the server's response will be unspecified, depending on the server's 36 configuration. 37 38 You should also be aware that many HTTP/1.1 servers do not have this feature 39 enabled, so that when you attempt to get a range, you'll instead get the whole 40 document. 41 42 FTP and SFTP range downloads only support the simple 'start-stop' syntax 43 (optionally with one of the numbers omitted). FTP use depends on the extended 44 FTP command SIZE. 45 46 If this option is used several times, the last one will be used. 47
