Clients can detect a weak ETag because it must begin with "W/ ". Two entities from the same URL with the same weak ETag should be mostly the same, whereas two entities from the same URL with the same strong ETag must be exactly the same. This is done by having the server provide ETags for all GET response bodies that can be cached, and the client sends the ETag back in requests for the same resource. It's useful for the client to be able to ask a Web server if an entity that the client previously cached is still up to date. An entity is the information transferred as the payload of a request or response. Appendix A.ETags identify a particular instance of an entity.
