If you want to check your Web browser's settings, you can find them in Preferences or Internet Options. Cached pages display more quickly than pages which must be retrieved from a Web server, and your Web browser uses cached pages whenever it determines that a Web page has not changed on the originating Web server since the last time you viewed it. A few Web browsers erroneously retrieve pages from cache even though those pages have changed on originating Web server. This misbehavior may cause you to see false data. While this setting is slower to display Web pages, its data are more likely to be accurate.
