Websites go offline. They move, occasionally suffer from temporary unavailability or errors, or become slow to respond because of technical difficulties or a period of high user demand. Some websites may not be reachable from your particular Internet connection or network. In those cases, when you need the information right away, you need a mirror of that website’s content.

所有的网站都有可能因为某种原因而被注销,或者变更地址,又或者因为技术原因无法登陆。有些网站可能因为你所在的网络原因而无法进入(例如被墙)。如果你急需这个网站里面的一些信息,你可以利用这个网站的一些镜像文件。

Unless a site explicitly denies it, Google creates a full copy of a site’s pages on its servers. When you do a Google search, you can notice that there are light blue links on the bottom right of each result. One of these — the Cached link — is the doorway to Google’s copy of a site.

Google对所有它索引了的网站都建立了相应的备份,除非有些网站明令禁止这样做。当你搜索的时候,你会看到所有的搜索链接下面都有一个the cached link,这个链接就可以进入Google的备份文件。

For example, if Lifehacker.com is down (although that never happens!)  But you need the article published there about creating a DVD photo slideshow for Mom’s birthday tomorrow, you can execute a Google search to find that article (site: lifehacker.com DVD photo slideshow). The results will look something like Figure 10-18; click the Cached link to see the article that you need, courtesy of Google.

例如,如果LifeHacker.com这个网站挂掉了(虽然这是不可能发生的事),但是你又想在它里面找一些文件。你就可以在Google里面搜索这个文件(例如site:lifehacker.com DVD).搜索结果如图10-18,这时,点击the cached link。就可以看到相关的文件了。

Alternatively, you can simply view Google’s copy of a site’s front page by using the cache: operator. That is, simply search for cache: lifehacker.com.

另外,你也可以通过Google的cache运算符来搜索网站的首页备份。例如:Cache: lifehacker.com.
