htaccess 如何将 www.domain.com 和 domain.com 重定向到 www.realdomain.com
我为一堆域设置了 htaccess 重定向，使其全部指向我的主域 - 但是它们仅将 domain.com 重定向到 www.realdomain.com，如果您点击 www.domain.com 重定向不会发生。
这是我所拥有的（每个域都会复制 rewritecond 和 rewriterules）：
Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.realdomain.com/$1 [R=301,L]
我对正则表达式的了解有点有限，但我认为它会查找以 domain.com 开头的地址，因此这是有道理的与 www.domain.com 不匹配。
有没有办法让正则表达式匹配它们，而不必将我已有的规则数量增加一倍？
I have an htaccess redirect set up for a bunch of domains to all point towards my main domain - however they only redirect domain.com to www.realdomain.com, if you hit www.domain.com the redirect doesn't take place.
Here's what I have (rewritecond and rewriterules are replicated for each domain):
Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.realdomain.com/$1 [R=301,L]
My knowledge of regexp is a bit limited but I gather that it looks for an address BEGINNING with domain.com, so it makes sense it wouldn't match www.domain.com.
Is there a way I can make that regexp match both of them without having to double the number of rules I already have?

您可以选择将其更改为
rewritecond %{http_host} ^(www\.)?domain.com [nc]来匹配www.You can have it optionally also match
www.by changing the line torewritecond %{http_host} ^(www\.)?domain.com [nc]
