404 : 请求的网页不存在(不排除日后该链接有效的可能性)；
410 : 请求的网页不存在(永久)；
200 : 服务器成功返回网页
302 : 网址临时重定向(跳转)
301 : 网址永久重定向
需要说明的是，大部分搜索引擎将“404”与“410”状态同等对待，如Google。
当搜索引擎在请求某个Url时得到“404”状态回应时，便会知道该网页在网站内不复存在，从而在索引数据库中将其删除，——当然，这个删除过程有可能需要很长时间——而当搜索引擎得到“200”状态回应时，则会认为该url是有效的，并将其回到到索引数据库中。
404错误页返回“200”状态码的后果
如果网站的自定义404错误页面在url无效时不返回“404”状态码而代之以“200”，会发生什么情况呢？很明显，搜索引擎会认为这个“根本不存在的”网页在网站内是存在的，这会导致很多问题，影响网站的最终SEO效果。
回复 2# 的帖子
一键安装LNMP用的伪原创，做了301，网站运转正常，不带WWW有可以正常跳，规则：
server
{
server_name 120j9.com;
rewrite ^(.*) http://www.120j9.com$1 permanent;
}
