   * Set the stream to be uploaded by this channel. 
   * History here is that we need to support both streams that already have header (eg.
   * content-type & content-length) information prepend to the stream (namely plugins) 
   * as well as clients (composer, uploading application) that want to upload data streams 
   * without any knowledgle of protocol specifications.  For this reason, we have a special
   * meaning for contentType.  See below.
   * 
   *   @param stream
   *          Stream to be uploaded by this channel
   *   @param contentType
   *          If the contentType is nsnull, the protocol will assume that no content 
   *          headers are to be added to the uploaded stream and that any required
   *          headers are already in the param |stream|.  In HTTP's case, if you do
   *          specify a content header, the implemention should prepend this as a 
   *          content-type header to the uploading stream.  In FTP's case, this 
   *          parameter is ignored. 
   *   @param contentLength
   *          Use of -1 assumes that the data length is returned by the |stream|'s 
   *          Available() method.
