将所有通配符子域重定向到根域 [英] redirect all wildcard subdomains to root domain

问题描述

好的，我已经进行了大量搜索，但仍然找不到足够具体的内容来解决我的问题.

Okay, I have done a fair amount of searching but still can't find something specific enough to handle my problem.

现在我有一个 DNS 记录，可以将所有其他子域重定向到我的服务器.我要问的是什么会使 example.mydomain.com 返回 HTTP/1.1 301 并重定向到 mydomain.com

Right now I have a DNS record that redirects all other subdomains to my server. What I'm asking is what would make example.mydomain.com return HTTP/1.1 301 and redirect to just mydomain.com

如果这已经被覆盖，我很抱歉，我找不到任何足够具体的东西.

My apologies if this has been covered, I just couldn't find anything specific enough.

推荐答案

使用 RewriteCond 来匹配除 mydomain.com 和 301 重定向之外的域:

Use a RewriteCond to match domains other than mydomain.com and 301 redirect them:

RewriteEngine On
# If the domain (any domain) is not exactly mydomain.com...
RewriteCond %{HTTP_HOST} !^mydomain\.com$ [NC]
RewriteRule (.*) http://mydomain.com/$1 [L,R=301,QSA]

您还可以更具体地查找 mydomain.com 的子域.上面的将匹配任何其他域.

You can also look more specifically for subdomains of mydomain.com. The one above would match any other domain.

# Match only subdomains of mydomain.com
RewriteCond %{HTTP_HOST} ^(.+)\.mydomain\.com$ [NC]
RewriteRule (.*) http://mydomain.com/$1 [L,R=301,QSA]
