◆ downloadAndReturn()

downloadAndReturn (   $url,
  $from = null,
  $to = null,
array  $params = array() 

Download a part (or the whole) of a remote URL and return the downloaded data. You are supposed to check the size of the returned data. If it's smaller than what you expected you've reached end of file. If it's empty you have tried reading past EOF. If it's larger than what you expected the server doesn't support chunk downloads.

If this class' supportsChunkDownload returns false you should assume that the $from and $to parameters will be ignored.
