2.3.1.1.9 ExpectedSizeBeforeAppendChunk

ExpectedSizeBeforeAppendChunk

Optional. Provides the expected file size (in bytes) of the file to which the uploaded chunk will be appended. It is used by upload requests with “Upload file middle chunk” or Upload file last chunk” actions, in order to allow the server to validate the append operation. If the file size provided by the request does not match the size of the existing file in the server, an exception is raised and the request is aborted.
