Hello,

Your "A" strategy will be easily implementable using the proxy-cache
Proximity (the new one, NOT the currect RCx tree). You need a new
"router", based on an existing one.

See the

http://trac.abstracthorizon.org/proximity/wiki/Release_2

"Architecture" link. All you would do is the following:

simply subclass the group-based repository (or repo-based, as you
like) and override the single doRetrieveItem method, to behave as you
said: do super.doRetrieveItem and if fails, retry it without
classifier, sign it, store it, and return it.

Also, the router could use the classifier as "key selector". It could
act as "plain" group-based (or repo based) router for requests without
classifiers.

The release of Px2 will replace the RCx line, but is a little delayed.
The core (as it is written on wiki and much more) is already
implemented and Web frontend is still in development.


Hope helps,

~t~

A) in a caching-proxy repo, when asked for a jar with
classifier "signed-by-foo", it returns the one it has, or it signs it on the
fly, caches it and returns it.
