Caches are archived copies that some search engines, such as Google, keep of the

Web pages they index.  The cached copy stored by Google will have a URL that is

different from the original URL.  Because Web sites often change rapidly, caches are the

only way to access pages that have been taken down, revised, or have changed their

URLs for some reason.  For example, a magazine might place its current stories under a

given URL, and replace them monthly with new stories.  If a user wanted to find an

article published six months ago, he or she would be unable to access it if not for

Google's cached version.  

Some sites on the Web serve as a proxy or intermediary between a user and

another Web page.  When using a proxy server, a user does not access the page from its

original URL, but rather from the URL of the proxy server.  One type of proxy service is

an  anonymizer.   Users may access Web sites indirectly via an anonymizer when they

do not want the Web site they are visiting to be able to determine the IP address from

which they are accessing the site, or to leave  cookies  on their browser.

servers can be used to attempt to translate Web page content from one language to

another.  Rather than directly accessing the original Web page in its original language,

  A  cookie  is  a small file or part of a file stored on a World Wide Web user's

computer, created and subsequently read by a Web site server, and containing personal

information (as a user identification code, customized preferences, or a record of pages

visited).
