When I request a web page I'm not looking at it on the server that's storing it. It's downloaded to my PC via the web by my ISP (comcast). Thats why if my cable connection is broken, the page is still displayed on my screen.
Comcast transfers the pages I request but only stores my emails, while I'm offline, untill I request them. As part of there service they set aside two blocks of their storage capacity, that I can use. One for pictures and such and one if I wanted to have a small site. I choose not to use them so they are storing nothing for me, except emails.
