How to redirect all requests to http(s)://www.domainname.tld/

Hello,

I want to setup my Apache 2.4 server in a way to redirect all requests in following way:

http://domainname.tld/ to http://www.domainname.tld/ and https://domainname.tld/ to https://www.domainname.tld/

my vhost conf file is as follows:

<VirtualHost *:80>

	ServerName www.domainname.tld

	ServerAlias www.domainname.tld

	DocumentRoot ......

	# other vhost settings
	# ...
	# ...
	# ...

</VirtualHost>

<VirtualHost *:80>
	ServerName domainname.tld
	ServerAlias domainname.tld
	Redirect "/" "http://www.domainname.tld/"
</VirtualHost>

<VirtualHost *:443>

	ServerName www.domainname.tld

	ServerAlias www.domainname.tld

	DocumentRoot /..............

	# SSL configuration
	# ...
	# ...
	# ...

</VirtualHost>

<VirtualHost *:443>
	ServerName domainname.tld
	ServerAlias domainname.tld
	Redirect "/" "https://www.domainname.tld/"
</VirtualHost>

I don’t have any rewrite rules in my htaccess file.

http redirect works ok, but if i open https://domainname.tld my request is redirected to the very first vhost configuration on my server.

Please can you tell me what’s wrong with my vhost configuration?

As far as I know the best way to achieve this type of redirect is to modify the vhost configuration instead of adding rewrite rules to the htaccess file. The very best way to solve this doesn’t involve mod_rewrite at all, but rather uses the Redirect directive placed in a virtual host for the non-canonical hostname(s).

Please share your comments! Thank you in advance!

How To Avoid SSL Certificate Mismatch Errors When Redirecting Multiple Virtual Hosts - Because the SSL protocol encapsulates HTTP traffic, adding or removing the ‘www’ subdomain must be done correctly.

https://www.tombrossman.com/blog/2014/avoid-certificate-mismatch-when-redirecting-multiple-ssl-virtualhosts/

<VirtualHost :443>
	ServerName EXAMPLE-1.com
	SSLEngine on
	SSLCertificateFile      /PATH/TO/CERT.crt
	SSLCertificateChainFile /PATH/TO/CHAIN/FILE.pem
	SSLCertificateKeyFile   /PATH/TO/KEY.key
	RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</VirtualHost>

<VirtualHost :443>
	ServerName WWW.EXAMPLE-1.com
	...
</VirtualHost>

All you need to do is add the certificate paths inside the redirect block so the key exchange can take place prior to the redirect.
