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.
