yes, fairly... In fact, I wonder why it works in the
code I wrote/used; I suppose, in that code, the redirect
is invisible. does the XSLT document() function let you
know when a redirect occurred? I doubt it. I know this
is an issue in javascript/XMLHTTPRequest standardization.

I was about to argue that in the case of
C:  GET U1
S1: 302 found; location: U2
S2: 200 OK body2

then body2 is a representation of what U1 identifies
as well as what U2 identifies... but that could cause
relative URIs to go screwy.


I don't have a strong feeling of that the right answer is here.
