This section provides general information about the SCSP READ method that applies to both named and unnamed objects.

Range | Returns |
|---|---|
0-499 | First 500 bytes of the object |
500-999 | The second 500 bytes |
-500 | Last 500 bytes |
0-499, 500-999 | First 1000 bytes |

NoteRange headers are not compatible with either integrity seals or the ContentMD5 header because both require a hash of the object's entire contents. The connection is closed as if the integrity seal or the Content-MD5 was invalid if the range is not set to a value greater than or equal to the size of the object. |
READ requests that include invalid Range headers (for example, ranges that do not exist existing in the object) cause Swarm to respond with a 416 (Range not satisfiable) error. A successful response to a READ that includes one or more Range headers is 206 (Partial content). Data in the requested ranges are included in the 206 response.
