.htaccess 301 将主页重定向到子域

Question

I would like to redirect my home page to a subdomain in .htaccess. Ive tried several different ways I found online. None have worked.

https://example.com/index.com to https://sub.example.com/index.com

Answer 1

Assuming that you actually want to redirect all requests to that subdomain this probably is what you are looking for:

RewriteEngine on 
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule ^ https://sub.example.com%{REQUEST_URI} [R=301,L]

It probably makes sense to start using R=302 temporary redirections first. And to only change those to R=301 permanent redirections once everything works as desired. That prevents nasty caching issues on the client side. Also you always want to test using a fresh anonymous browser window.

Best place to implement such rules is in the central http server's host configuration. If you do not have access to that you can use a distributed configuration file instead (".htaccess"), if you have enabled the consideration of such files in the http server ... Above rules will work likewise if that file is placed inside the DOCUMENT_ROOT folder of the http host.
