However, Zope seems to send a bogus ETag header. The HTTP spec says that the ETag must uniquely identify the current incarnation of the entity. Especially, the ETag should change, when the entity is modified. But Zope sends empty "ETag" headers, allowing HTTP compatible caches to cache the pages. This seems to be a bug with the consequence of unanticipated caching problems.
