redirect from subdomain to domain + .htaccess
提问by earl
Is is possible that i can configure RewriteRule for more then one domain.
我可以为多个域配置 RewriteRule 是可能的。
Like my requirement is My current domain name www.maindomain.com and let say i have three domian and subdomain the subdomain url is example1.maindomain.com example2.maindomain.com example3.maindomain.com
就像我的要求是我当前的域名 www.maindomain.com 假设我有三个域和子域，子域 url 是 example1.maindomain.com example2.maindomain.com example3.maindomain.com
Now i want when ever user try to access www.example1.com it should get the content of example1.maindomain.com and the same for example2, example3
现在我希望当用户尝试访问 www.example1.com 时，它应该获取 example1.maindomain.com 的内容，对于 example2、example3 也是如此
I am using apache + passenger.
我正在使用 apache + 乘客。

First, write a condition that matches all the domain names you want to redirect. Using the matched part of the domain, write a rule that rewrites to the target subdomain URLs. So, given the desired mapping stated in your question, something like the following should do the trick:
首先，编写一个与您要重定向的所有域名匹配的条件。使用域的匹配部分，编写重写目标子域 URL 的规则。因此，考虑到您的问题中所述的所需映射，以下内容应该可以解决问题：
RewriteCond %{HTTP_HOST} ^www\.(example[123])\.com$ [NC]
RewriteRule ^(.*) http://%1.maindomain.com/ [L,R]
The above rewrites from e.g. www.example1.comto example1.maindomain.com. Similarly, if you need it the other way round:
上面从 eg 重写www.example1.com为example1.maindomain.com. 同样，如果您反过来需要它：
RewriteCond %{HTTP_HOST} ^(example[123])\.maindomain\.com$ [NC]
RewriteRule ^(.*) http://www.%1.com/ [L,R]
This would rewrite e.g. example2.maindomain.comto www.example2.com.
这将重写例如example2.maindomain.com到www.example2.com.
