如何在子域重定向后禁用与htaccess的直接链接？

I have a subdomain which redirects to a specific directory address. How can I disable that directory address if it is accessed directly?

i.e. sub.domain.com redirects to domain.com/sub. When I access domain.com/sub directly it should redirect to error 404.

Thanks

When I access domain.com/sub directly it should redirect to error 404.

You can use this rule as first rule in sub/.htaccess:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^sub\. [NC]
RewriteRule ^ - [L,R=404]

In htaccess in your document root, add this :

RewriteEngine on

RewriteCond %{HTTP_HOST} !^sub.domain.com$
RewriteRule ^folder - [R=404,L]

This will redirect all requests that start with /folder to 404 page if requested host is not sub.domain.com .
