我有一个htaccess的相关问题。

I have a .htaccess related question.

例如，如果我有两个域名，a.com和b.com。都指一台主机（b.com是a.com的域别名）。我想这访问者访问a.com将被称为URL以WWW（http://www.a.com）。至于 http://b.com 的游客将被提交给WWW网址上（http：//www.b .COM）。

For example, if I have two domain, a.com and b.com. All referring to one host (b.com is domain alias of a.com). I want visitor that visit a.com will be referred to url with www (http://www.a.com). As for the visitor of http://b.com will be referred to the www url (http://www.b.com).

我怎样才能做到这一点跟的.htaccess ??

How can I do this with .htaccess??

推荐答案

您可以尝试用2重写规则

You could try with 2 rewrite rules

RewriteEngine On

RewriteCond %{HTTP_HOST} ^a.com$ [NC]
RewriteRule ^(.*)$ http://www.a.com/$1 [L,R=301]

RewriteCond %{HTTP_HOST} ^b.com$ [NC]
RewriteRule ^(.*)$ http://www.b.com/$1 [L,R=301]
