重定向所有子域名的主域名页面 [英] Redirect any sub domain to a page on main domain
问题描述
只是一个quicky真的。我希望能够重定向任何人谁类型的一个 subdomain.mydomain.com 被重定向到一个网页上我的主要领域。即如果我输入： answers.mydomain.com 我会被重定向到 mydomain.com/suberror 例如
Just a quicky really. I want to be able to redirect anybody who types a subdomain.mydomain.com to be redirected to a page on my main domain. i.e If I typed: answers.mydomain.com I would be redirected to mydomain.com/suberror for instance.
我想这是可能的话一个普遍的规则，因为我认为这将是更容易添加语句排除，我不希望被重定向而不是增加语句包括所有其他子域的任何子域。我需要把这个使用的.htaccess 文件的方式。
I would like this to be a universal rule if possible because I thought it would be easier to add statements to exclude any subdomains that I didn't want to be redirected rather than add statements to include every other subdomain. I will need to this using a .htaccess file by the way.
请你能告诉我，如果这是可能的，如果是这样，怎么....在此先感谢！
Please could you tell me if this is possible, and if so, how.... Thanks in advance!
推荐答案
尝试在你的.htaccess文件添加以下内容到一个合适的位置：
Try adding this to an appropriate place in your .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^answers\.mydomain\.com$ [NC]
RewriteRule ^ http://mydomain.com/suberror [L,R]
只要请求的主机是 answers.mydomain.com ，该规则将被应用。随着正则表达式匹配设置为 ^ ，任何的URI将匹配和目标将被重定向到的 http://mydomain.com/suberror
As long as the requested host is answers.mydomain.com, the rule will be applied. With the regex match set to ^, any URI will match and the target will be redirected to http://mydomain.com/suberror
如果你想被重定向到/ suberror只有特定URI请求，你可以调整 ^ 适当的东西。
If you want only specific URI requests to be redirected to /suberror, you can tweak the ^ to something appropriate.
编辑：
对于所有的子域（包括www.mydomain.com）：
For all subdomains (including www.mydomain.com):
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(.+)\.mydomain\.com$ [NC]
RewriteRule ^ http://mydomain.com/suberror [L,R]
要排除www.mydomain.com，在重写规则之前加入这一行：
To exclude www.mydomain.com, add this line before the RewriteRule:
RewriteCond %{HTTP_HOST} !^www\.mydomain\.com$ [NC]
