In Safari I keep seeing old pages, like the CNN home page from the 2nd of August or MR from the 5th of August. When I refresh it goes back to normal why is this?
I have seen the same problem if you go to a site, click a link, click back button (not re-enter URL), go to a different site, go back to the original site. You will have an old version (atleast on my system, and I have seen it happen many times.)
I then swapped over to Webkit and it hasnt happened since.
