的.htaccess重写子域

下面是我目前的code：

Here is my current code:

RewriteCond %{HTTP_HOST} !^example\.com [NC] 
#RewriteCond %{REQUEST_URI}!^something
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com 
RewriteRule (.*) something/%1/$1 [QSA,L]

我的目标是改写的http：//*.example.com/whatever 到 http://example.com/something/* /不管，假设 * 是相同的两个和任何是相同的两个。不过，我相信这是造成一个无限循环不知何故，所以我补充说，注释掉线（的RewriteBase是/ BTW），但如果我取消，那么整个网站是一个500响应code。如果没有这一行，只有子域错误。

My goal is to rewrite http://*.example.com/whatever to http://example.com/something/*/whatever, assuming * is the same for both and whatever is the same for both. However, I believe this is causing an infinite loop somehow, so I added that commented out line (RewriteBase is / btw), but if I uncomment then the entire site is a 500 response code. Without that line, only the subdomains error.

我在做什么错了，我怎么能解决这个问题？我已经配置了服务器，所以，只要被重定向到我的public_html文件夹中。

What am I doing wrong, and how can I fix this? I have already configured the server so anything gets redirected to my public_html folder.

编辑：为了澄清，我试图做一个内部重定向，而不​​是外部

For clarification, I am trying to do an internal redirect, not external.

编辑：没有一个标志内部重定向看来。有没有我可以看到破碎的重写规则的实际错误消息的任何地方吗？如果我知道什么是错了，我将能够有更好的机会修复它。

There is not a flag for internal redirect it seems. Is there any place I can see the actual error message for the broken rewriterule? If I knew what was wrong I would be able to stand a better chance of fixing it.
