Dan,
can a http URI refer transiently or accidentally to some address?
Which term do you suggest for something which permanently refers to a (unique, permanent) web address, and
which differs if and only if the web address differs?

Dan,
in http://www.w3.org/TR/uri-clarification/ I read "An http URI is a URL"
. So I concluded that a different http URI is a different URL (address).
At this I assumed, that all http URIs which refer to the same address
(case insensitive), are defined as "identical". Is this correct?
I'd rather they'd have said "URL" is a technically obsolete but common colloquial term for http and
http-like URIs. Identity of identifiers is tricky because you have to try to distinguish between identifiers
which accidentally of transiently refer to the same thing, versus those where it is built-in to the
definition of the scheme (eg. the port 80 and domain name canonicalisation rules).
