我有两个重定向（一个用于HTTP，一个用于HTTPS）：

I have two redirects (one for http and one for https):

# Option 1a: rewrite www.example.com → example.com

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTPS} !=on
    RewriteCond %{HTTP_HOST} ^www.(.+)$ [NC]
    RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]
</IfModule>

# Option 1b: rewrite https://www.example.com → https://example.com

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTPS} on
    RewriteCond %{HTTP_HOST} ^www.(.+)$ [NC]
    RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]
</IfModule>

是否有可能将它们合并，并删除的子站点的HTTP和HTTPS有一个规则集（无需指定确切域，像现在的规则）？

Is it possible to combine them, and remove the subdomain for both http and https with one ruleset (without having to specify the exact domain, like the current rules)?

推荐答案

下面是你可以两个规则组合成一个没有硬编码主机名：

Here is how you can combine both rules into one without hardcoding hostname:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP_HOST}#%{HTTPS}s ^www.([^#]+)#(?:off|on(s)) [NC]
    RewriteRule ^ http%2://%1%{REQUEST_URI} [R=301,L]
</IfModule>
