This specification clearly states:
...
The response contains one of more header lines of the form
Location: <url> String CrLf
Which specify alternative addresses for the object in question.
...
No mention is made of URI *at all*.
However, when the specification dated 5 November 1993 came out *after
we had implemented the previous one*, Location had been completely
removed, and it had been replaced by URI. Despite numerous attempts to
get someone from CERN to put Location back in at least as a
depreciated form of URI, the specification still has no mention of
Location.
And so we see that no good deed goes unpunished.
