Generally, last-modified values received or used by these systems will support transparent and efficient caching, and so HTTP/1.1 origin servers SHOULD 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."
