      Description

      The http protocol allows clients to request part of a file rather than the entire file as defined here:

      http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.5

      The server outputs the http header

      Accept-Ranges: bytes

      after which a client may request a partial download, e.g.

      GET /downloads/selenium.zip HTTP/1.1
      Referer: http://qa1-za.sakaiproject.org/downloads/
      Accept: /
      Range: bytes=2350112-

      The access servlet should support partial downloads as this may speed up downloading through download managers, and also supports resuming downloads that have been interrupted.
