Re: URL-Reference / "empty URL" question

The way I think of it myself is that when you interact with
a resource on the network ("http://whatever.com/blah")
or even a local file ("file:///c|/downloaded/blah") and
recieve some content from that resource and are viewing
it, the viewer has another implicit resource:

  "the copy of the content that is being viewed now"

Let's give it its own URL scheme
   "this:"
where the scheme-specific part of "this:" is
empty. Then what we want to assert is that URL references
of the form "#xxxx" are *not* relative
to the BASE at all, they're always relative to
to "this:". That is,

    <A HREF="#blarg">...</A>

is equivalent to

    <A HREF="this:#blarg">...</A>

and different from

    <A HREF="file://localhost/download/blah#blarg">...</A>

even when the buffer was read from "file://localhost/download/blah"
in that following a "file:" link might well re-fetch the
data in the case where the file has actually changed.

I know many browsers have built-in URLs for some operations
("about:", "globalhistory:") and vaguely remember some
reference to "back:" and "forward:" somewhere; but what
we need to explain "#blarg" is "this:".

Larry
