A repository of Web pages used to speed the delivery of those pages to users. Many ISPs maintain "proxy servers" that store millions of pages copied from the Web. When a user requests a page stored on a proxy, the ISP delivers the page quickly from the proxy rather than using the Web server to retrieve the page from the Net (which can take much longer). There have been some problems with this, however (see: AOL) because content on the Web is dynamic and not meant to be stored.
