Making someone reload a page in its entirety every time they go past it is not good for you or them. It's far better to have a sensible caching period, short enough for sites that's appropriate to, longer for sites that don't change that much. It's the height of idiocy to have to keep on reloading some page that has not changed. I've come across sites where I've loaded a page, followed one link, immediately found it not to be what I wanted, backtracked a page mere seconds later, and had to sit through another half minute of it reloading. This sort of stupidity is typical of sites that think they're newsworthy, with dozens of adverts on the pages, smatterings of articles on the one page, etc. -- Don't send private replies to my address, the mailbox is ignored.
