nsIResumableChannel

From MDC

This interface is meant to be implemented by the channels that support resuming broken downloads (e.g. Necko's HTML and FTP channels).

nsIResumableChannel is defined in netwerk/base/public/nsIResumableChannel.idl. It is scriptable and unfrozen (hasn't changed since Mozilla 1.8a4).

Inherits from: nsISupports

See Implementing Download Resuming for information on using this interface.
