“404 error page” - A common term to every internet users. But do you know from where it comes. In an office on the fourth floor (Room 404), an ambitious group of young scientists at CERN (Switzerland) located the World Wide Web’s central database. When the record of database started to increase, not only the amount of requests grew, but also increased the amount of requests that could not be fulfilled. Generally it occurs, because of requested a file in the incorrect name. Soon these error requests were replied with a regular message: “Room 404: file not found”. From where we get our today’s “404 error page”.
“404错误页” - 每个互联网用户都可能遇到的一个错误提示。但是，你知道它为什么这样提示的吗？CERN（瑞士）位于万维网的中央数据库的四楼（404室），这是个热情向上的青年科学家小组办公室。当数据库记录开始增加后，不仅点击请求量增长，而且也增加的请求无法得到满足。通常在这样的情况下要提示不正确的文件的名称。不久，这些错误的要求得到了答复与消息：“404室：找不到文件”。最后我们就得到了今天的“404错误页”。
