Sounds like an over-aggressive cache.  Could be your browser or ISP.

IMHO that would be wrong.  ISTM perfectly reasonable that the validator
reports should be cacheable, and messing that up is going to annoy a
lot of users.  OTOH, it might possibly help with some caches if the
validator were to compute an Etag, and it could also set Last-Modified
to that of the page being validated.
