Blogger doesn’t use dynamic server side scripting like PHP or MySQL to generate its page every time you request it. It has to “publish” the blog into HTML once you make the changes. So although the web page is technically updated, your browser doesn’t recognize it since the older page has already been cached. With dynamic blogs the server side script when executed automatically loads the blog from the database each time it is requested and so you don’t have this problem.My mouse, finger and even the refresh button have had a bit of a workout this week & are very tired!! via TitaniumGeek.
