OK, on further consideration after posting, I've reached the view that
the 2.0.49 patch should be modified.  I'd propose to run the same
transformations on Set-Cookie headers from the backend, but move
the rewriting - along with the rewriting of Date and Location headers
(ap_proxy_date_canon and ap_proxy_location_reverse_map) into
ap_proxy_read_headers.  That actually both cleans up the code (reduces
adhockery) and makes it more efficient (reduces table operations),
as well as making my patch orthogonal to yours.

That I still find puzzling.  Perhaps there's a URL into the mail
archives from your previous discussion that would explain it?
