help: upper cache

[virus1]

upper cache.. i was told by a friend that it is a way to download images to a computer only once, even though you may have it in many places. for example, a title bar. so it doesn't have to download the image again every time they go to a new page wasting your precious bandwidth. if anyone can tell me what it is better, how to do it, or where to find out how to do it, i would really appreciate it..
