Hi Graham,

Thanks for the revie= w again.

Hi Matthew,

I think the main body of the document is a lot crisper now.=C2=A0 I have a = couple of comments from a fairly quick scan.=C2=A0 The main substantive com= ment is that local access can occur when the file URI contains a host name = which is the same as that for the host from which access is being attempted= .


You know what, I think you= 9;re right, and I've been suffering from confirmation bias. I just test= ed it again, and both Chromium and Firefox do treat my machine's networ= k name the same as "localhost". Windows and IE do it the way I= 9;ve documented in the draft, but it seems they're the only ones. (If o= nly I'd had mnot's test suite ...)

I'll change all the appropriate parts to say the right thing.

I've not done a detailed read through of the appendices - much of the m= aterial there is outside my experience.


Appendices A and B are the ge= nerally useful ones.


...

Section 2:

[[
=C2=A0 =C2=A0Some file systems allow directory objects to be treated as fil= es in
=C2=A0 =C2=A0some cases.=C2=A0 This can be reflected in a file URI by omitt= ing the
=C2=A0 =C2=A0trailing slash "/" from the path.=C2=A0 Be aware tha= t merging a relative
=C2=A0 =C2=A0URI reference to such a base URI as per Section 5.2 of [RFC398= 6]
=C2=A0 =C2=A0could remove the directory name from the resulting target URI.=
]]

I think the second sentence is wandering into local implementation details.= =C2=A0 I'd suggest focusing more on the idea that the trailing slash sh= ould be included in URIs that refer to directories.


I preferred stating the use-c= ase and the potential problems it causes, rather than making a judgement ca= ll. I'm not 100% invested in it, though, and can cut it back if it'= s too far the wrong way.


...


Section 3:

[[
=C2=A0 =C2=A0A file URI can be dependably dereferenced or translated to a l= ocal
=C2=A0 =C2=A0file path only if it is local.=C2=A0 A file URI is considered = "local" if
=C2=A0 =C2=A0it has no "file-auth", or the "file-auth" = is the special string
=C2=A0 =C2=A0"localhost".
]]

There's also the case when the hostname resolves to the local host.


Yep, I will include that when= I make the change.
