Re:我现在有一个网站我想把bbs.xxx.com解析到www.xxx.com的耳机目录，我要怎 & ..

经常会碰到这样的情况，其他网站链接你的站点时，会用下面的链接：

www.example.comexample.com/www.example.com/index.htmlexample.com/index.php

而这样导致：你站点主域名的pr值分散到其他几个URLs了。

如果你用301重定向把其他三个URL转到www.example.com PR也就集中在主域名：www.example.com 了。301重定向具体办法：

设置.htaccess文件(只适用于linux系统，并需要虚拟主机支持。)

使访问example.com/的时候就会自动转到www.example.com 在.htaccess文件里写上以下代码即可。RewriteEngine onRewriteCond %{http_host} ^mydomain.com [NC]RewriteRule ^(.*)$ http://www.mydomain.com/$1 [L,R=301]

注意：URL标准化的301重定向(以上代码)需要写在其他URL-rewrite代码之前。

下面给你一个别的网站的.htaceess文件设置，你可以参考下
