The byte-range to be sent to the server.

Syntax

 http.getRange([callback])
 http.setRange( range, [callback])

Default Value

""

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getRange([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setRange([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

If this property contains a non-empty string, a Range HTTP request header is added to the request. This header tells the server to only send a certain range of bytes.

The format of this property consists of a range of bytes specified by two numbers separated by '-' (e.g. "0-499")
