The ability to access recently-access website is not an illusion caused
by cached pages. I can get *fresh* content from those sites. It looks to
me like a DNS lookup problem -- the recently visited websites still have
the results of the previous lookups cached somewhere, so either no new
DNS queries are generated or the new DNS queries are answered with
cached answers somewhere (I don't have a good guess as to where that
might be though).
