* Updates the file based on a range specification.

|
*
|
|
* The first argument is the data, which is either a readable stream
|
|
* resource or a string.
|
|
*
|
|
* The second argument is the type of update we're doing.
|
|
* This is either:
|
|
* * 1. append
|
|
* * 2. update based on a start byte
|
|
* * 3. update based on an end byte
|
|
*;
|
|
* The third argument is the start or end byte.
|
|
*
|
|
* After a successful put operation, you may choose to return an ETag. The
|
|
* etag must always be surrounded by double-quotes. These quotes must
|
|
* appear in the actual string you're returning.
|
|
*
|
|
* Clients may use the ETag from a PUT request to later on make sure that
|
|
* when they update the file, the contents haven't changed in the mean
|
|
* time.
