Ticket #363 (closed design: fixed)

p4 2.4 Rules for When to Use Entity-tags and Last-Modified Dates notes at the end:
HTTP/1.0 clients and caches might ignore entity-tags. Generally, last-modified values received or used by these systems will support transparent and efficient caching, and so HTTP/1.1 origin servers still ought to provide Last-Modified values. In those rare cases where the use of a Last-Modified value as a validator by an HTTP/1.0 system could result in a serious problem, then HTTP/1.1 origin servers should not provide one.
What are these "rare cases", and how is a server to know when it's encountering one?
