StreamSource version which organises streaming via a temporary file. Streamed content can be populated via OutputStream provided by getTempFileOutputStream(). In order to set up the resource the following attributes are required to be set:

• tempFileName - name of the buffer temporary file

• fileName - the name of the downloaded file

Note: the streamed resource is by default configured to be not cached Note: the temporary file is attempted to be eagerly deleted once the streaming is over
