Cara Redirect Semua Url Domain Lama ke Domain Baru dengan .htaccess

Redirecting all URLs from olddomain.com to newdomain.com

So the example below is redirecting all URLs from olddomain.com to newdomain.com

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.olddomain\.com$
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} !^olddomain\.com$
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

You can also apply this to a subdomain – so the example below is redirecting all URLs from subdomain.olddomain.com to subdomain.newdomain.com

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^subdomain.olddomain.com$
RewriteRule ^(.*)$ http://subdomain.newdomain.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} ^www.subdomain.olddomain.com$
RewriteRule ^(.*)$ http://subdomain.newdomain.com/$1 [R=301,L]

Force a Directory Folder or WebSite to go over HTTPS SSL with htaccess

To force a website to use the secure protocol SSL running the whole site over HTTPS you can make a simple edit to the .htaccess file in the document root.

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]
To force a particular folder or directory to serve over SSL, create a .htaccess file in that folder and apply the following to it:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteCond %{REQUEST_URI} somefolder
RewriteRule ^(.*)$ https://www.domain.com/somefolder/$1 [R,L]
This assumes SSL is enabled on the domain on an Apache Web Server with the  mod_rewrite module enabled.

Redirecting WWW to non-WWW with htaccess

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
Just make sure you add it at the very top of the htaccess file.
