is absolutely meaningless, because the actual file size is not
related to the size of the documents retrieved. Worse even,
there are cases (and DynaWeb is one) where a single URL
can possibly reference documents that differ in an
arbitrary manner.
In other words, byte ranges are not generally applicable to
all objects accessible via a URL, so we cannot make this
a requirement.
How about adding another method instead?
