     276   Likewise, a validator is weak if it is shared by two or more
     277   representations of a given resource at the same time, unless those
     278   representations have identical representation data. For example, if the
     279   origin server sends the same validator for a representation with a gzip
     280   content coding applied as it does for a representation with no content
     281   coding, then that validator is weak. However, two simultaneous
     282   representations might share the same strong validator if they differ only
     283   in the representation metadata, such as when two different media types are
     284   available for the same representation data.
