You mean like implementing a POST to the cache_object:// data space?

Adding stuff to the cache directories alone is fairly trivial. The
problem lies with the internal indexing structures of Squid, which
retain a mirror of the meta data plus additional data for memory
management. If they are not updated Squid is likely to overwrite the new
content at any time.

Alex is looking into storage improvement stuff at present (RockStore
feature in the wiki). I think getting in touch with him would be a
benefit to both of you and see about collaborating work.
