I've noticed with iOS 5 Safari that when I bring up a webpage, press on a link, then press the back button I wind up with an older version of the webpage, not the version I had just viewed. It appears that Safari is caching this older version and using it instead of the latest version that I just displayed. Even if I refresh the page, press on a link and press the back button an older version of the page is displayed. Has anyone else seen this? Is there a setting I can change to stop this behavior? It is driving me crazy to come back to a page, start reading through it and realize that it the same page I read the day before.
