Purpose:	Returns the content of the file to be downloaded as a MEMPTR.
	This single method serves both the Desktop (AppServer) and the
	Web (REST) entry point of the DownloadFileBusinessTask
Notes:	The caller (DownloadFileBusinessTask) takes ownership of the
	returned MEMPTR and is responsible for releasing it
	(set-size (...) = 0).
	Implementations are expected to validate the requested file name
	and enforce any applicable authorization. The reference
	implementation rejects absolute paths (IHttp400Error), resolves
	the relative file name against a configured list of folders and
	raises an IHttp404Error when the file cannot be found.

Parameters:
pcFileName	CHARACTER
	The relative name of the file to download
Returns	MEMPTR
