What does emptying browser caches do? As for that matter, what does cleaning caches do? (I'm thinking of doing this bc my iBook is slightly laggy. It was very laggy last night so I repaired my HD, but it doesnt need to be repaired now, I just checked. I wont repair permissions again bc those are fine. The only two maintenance things left I think are the scripts [which I was told run on wake up] and the caches.) BTW, would emptying my browser caches help speed up my ibook maybe? i dont want to clean user and system caches bc I beleive that would require a reboot.
