Respawn Redux: Undeletable Cookies

The idea with etags is the server says "I'm giving you version XYZWABC of the data" and then if you rerequest it in the future you say "give me it but only if it's newer than XYZWABC". So the server gets to store some data in the cache as metadata.
One solution for new browsers might be to have an option to clear this data without removing everything from the cache.
One should rather say "Non-deletable cookies".
