The spec does not give a definitive answer to this one.  You have three 
reasonable choices:

/b/c/p - R3
/b/d/p - R3
where R3 is a copy of R1

/b/c/p - R3
/b/d/p - R3 
where R3 is a copy of R2

/b/c/p - R4
/b/d/p - R5
where R4 is a copy of R1
where R5 is a copy of R2

I have a slight preference for the third choice, since it is symmetric and 
is more structurally equivalent to /b.
But I think it is reasonable for a server to do 1 or 3, in case it is 
expensive for it to detect this situation (so I think the spec should 
leave this up to the server).

Cheers,
Geoff

binds and overwriting infinite-depth copies







Consider the following case.  There exist the following URLs and the
resource's they are bound to:

/a/c/p - R1
/a/d/p - R2
/b/c/p - R3
/b/d/p - R3

/b/c and /b/d are different collections.

What should happen if I do a COPY /a /b  with overwrite set to true?
Should the new /b/c/p and /b/d/p still be the same resource?  Keep in
mind that R3 may be a VCR.

Thanks for the help,
Tim
