I'm not understanding some things in Safari. I take the subway into work and of course once the train is underground there's no signal, so what I try to do is load some page to read, but half the time when I go back to Safari, it tries to reload the page from the beginning. And when I hit the back button to go to a previous page it does the same thing, I thought it caches previous pages. So I'm not understanding what the clear cache option is under settings is foe then. I'm new to the iPhone, just had it a few weeks now, and I just can't figure out the logic to Safari. Thanks for your help!
