Redirect rule | subdomain to main domain | htaccess

If you have a subdomain and want to redirect it to your main domain, then this post provides the redirect rule that you have to add in .htaccess file in sub-domain’s root directory.

For example, if your subdomain is img.example.com and main domain is example.com, then the htaccess redirect rule is

RewriteEngine On
RewriteCond %{HTTP_HOST} ^img\.example\.com  [NC]
RewriteRule ^(.*) https://www.example.com/$1 [L,R=301]

1. Replace example.com with your domain name
2. Replace img with your subdomain name
3. Create a empty .htaccess file at root directory of sub-domain
4. Copy the above updated redirect rule to htaccess file and upload
5. Check whether the subdomain pages redirect to main domain

So, if you enter img.example.com/page1.html, it redirects to https://www.example.com/page1.html
