RFC2616 section 14.9.1 What is Cacheable

      Indicates that all or part of the response message is intended for
      a single user and MUST NOT be cached by a shared cache. This
      allows an origin server to state that the specified parts of the
      response are intended for only one user and are not a valid
      response for requests by other users. A private (non-shared) cache
      MAY cache the response.

       Note: This usage of the word private only controls where the
       response may be cached, and cannot ensure the privacy of the
       message content.

"MUST NOT be cached by a shared cache" leaves very little room for
assumtions I would say. Squid is quite obviously a shared cache.
