让404页面返回正确的http status

日期:2011-08-10    阅读:43   分类:综合信息


一般虚拟主机都支持自定义404文件,但如果我们仅仅是指定一个文件之后,就万事大吉了么?

其实不是这样的,通过firefox插件httpfox可以看到,虽然到了404页面,但是返回的http code是200,那就意味着搜索引擎还是会收录这些页面,收录一堆404页面,这对一个网站的排名和收录都没有什么好处。

还有一点就是 搜索引擎会试图获取robots.txt文件,如果404页面没有返回正确的http code的话,那么引擎会得到一个不正确的robots.txt文件,这对于网站的收录也是有害的。

因此不光指定一个404页面,还有注意设置 Response.Status = "404 Not Found"。
