Question

网页有时能打开，有时打开出现Error 404--Not Found，是什么原因，应该如何解决？

打不开网页时出现的所有内容：
Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol --
HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the
Request-URI. No indication is given of whether the condition is temporary or
permanent.

If the server does not wish to make this information available to the client,
the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code
SHOULD be used if the server knows, through some internally configurable
mechanism, that an old resource is permanently unavailable and has no forwarding
address.

你访问的网页不存在，有可能是违规网站被关闭了，换其他的试试吧？经常有这种情况的的！有不安全的的因素就会关掉的！
