Dan,

   I thought this section was only applicable to proxies and intermediate 
caching servers / services?  Even if it is applicable to the User Agents, 
If the response reached the requesting agent then, IMHO, it is considered 
to be a private (non-shared) cache and will therefore cache the page.  I 
haven't found any reference that indicates what a User Agent should be 
considered, or how one might reset one.

                         Kevin
