how to redirect www to main domain using laravel htaccess-CodePudding

I have separate subdomain in laravel. I want when some one visit: www.shawn.com it will automatically redirected to shawn.com but if anyone visit hello.shawn.com its ok to visit.

but if another one visit www.hello.shawn.com it will redirect to hello.shawn.com I have managed htaccess to access this but its not working properly.

here is my htaccess:

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteRule ^(.*)$ public/$1 [L]
   RewriteEngine On 
   RewriteCond %{SERVER_PORT} 80
   RewriteCond %{HTTP_HOST} ^(www\.)?shawn\.com
   RewriteRule ^(.*)$ https://www.shawn.com/$1 [R,L]
</IfModule>

From your description it would seem you just need to remove the www subdomain, on whatever hostname is requested. Obviously the www subdomain must currently resolve to the same place.

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteRule ^(.*)$ public/$1 [L]
   RewriteEngine On 
   RewriteCond %{SERVER_PORT} 80
   RewriteCond %{HTTP_HOST} ^(www\.)?shawn\.com
   RewriteRule ^(.*)$ https://www.shawn.com/$1 [R,L]
</IfModule>

Your current directives are in the wrong order. I assume you must have another .htaccess file in the /public subdirectory (that does the actual routing through the Laravel front-controller)? In which case, the second rule (that redirects HTTP to HTTPS www) is never processed - just as well really, since this would expose the /public subdirectory (presumably hidden from the URL) and would seem to be the opposite of what you are trying to achieve (ie. removal of www).

Try the following instead:

RewriteEngine On

# Remove "www" subdomain from any hostname
RewriteCond %{HTTP_HOST} ^www\.(. ?)\.?$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]

# HTTP to HTTPS
RewriteCond %{SERVER_PORT} 80
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# Rewrite everything to the "/public" subdirectory
RewriteRule (.*) public/$1 [L]

The <IfModule> wrapper is not required and should be removed.

No need to repeat the RewriteEngine directive.

The %1 backreference in the first rule contains the hostname, less the www. prefix, captured from the preceding condition.

NB: Test first with 302 (temporary) redirects to avoid a potential caching issue. You will likely need to clear your browser cache before testing.

Salam. If do you need to access for subdomen www.hello.shawn.com then you must write this statement once again.

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteRule ^(.*)$ public/$1 [L]
   RewriteEngine On 
   RewriteCond %{HTTP_HOST} ^www\.hello\.shawn\.com
   RewriteRule ^(.*)$ https://hello.shawn.com/$1 [R,L]
</IfModule>
