Parameters

sourceUri: Uri

Specifies the Uri of the source blob. The value may be a Uri of up to 2 KB in length that specifies a blob. The source blob must either be public or must be authenticated via a shared access signature. If the source blob is public, no authentication is required to perform the operation.

sourceRange: HttpRange

Optionally only upload the bytes of the blob in the sourceUri in the specified range.

range: HttpRange

Specifies the range to be written as a page. Both the start and end of the range must be specified and can be up to 4MB in size. Given that pages must be aligned with 512-byte boundaries, the start of the range must be a modulus of 512 and the end of the range must be a modulus of 512 – 1. Examples of valid byte ranges are 0-511, 512-1023, etc.
