Apache的mod_rewrite规则作为子 [英] Apache mod_rewrite rule as subdomain

问题描述

怎么可以这样

http://some-url.com/?lang=en

改写这样：

http://en.some-url.com ???

用mod_rewrite？

via mod_rewrite?

推荐答案

您可以定义所有可能的子域languages​​pecific在some-url.com的虚拟主机，CONFIGFILE ServerAlias​​并添加以下重写规则

You could define all possible languagespecific subdomains as ServerAlias in the VirtualHost-configfile of some-url.com and add following rewriterule

RewriteEngine On
RewriteCond %{HTTP_HOST} ^some-url\.com$ [NC]
RewriteCond %{QUERY_STRING} lang=(.*)$
RewriteRule . http://%1.some-domain.com/? [R=301,L] 

在你的服务器端脚本，您可以通过检查称为HTTP_HOST服务器/ CGI变量得到实际的语言（PHP中，这将是 $ _ SERVER ['HTTP_HOST'] 而在ColdFusion的这将是＃CGI.HTTP_HOST＃）

In your serverside script you can get the actual language by checking SERVER/CGI variable called HTTP_HOST (in php this would be $_SERVER['HTTP_HOST'] while in ColdFusion this would be #CGI.HTTP_HOST#)
