Apache2 redirect https://www to https://non-www - apache

Question

I want to redirect https://www.mydom.com to http://mydom.com
I have an mydom.conf into apache2/sites-available/
mydom.conf:
#HTTP(www/non-www) -> HTTPS(non-www)
<VirtualHost *:80>
ServerName mydom.com
ServerAlias www.mydom.com
Redirect permanent / https://mydom.com/
</VirtualHost>
#ACTIVATE HTTPS AND REVERSE PROXY -> test-1.0.0
<VirtualHost _default_:443>
SSLEngine On
SSLCertificateFile /opt/ssl/new/mydom_com.crt
SSLCertificateKeyFile /opt/ssl/new/mydom_com.key
SSLCertificateChainFile /opt/ssl/new/mydom_com.ca-bundle
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
ServerName mydom.com
ServerAlias www.mydom.com
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:8080/test-1.0.0/
ProxyPassReverse / http://127.0.0.1:8080/test-1.0.0/
</VirtualHost>
With this mydom.conf It works partial.
Domains http://mydom.com and http://www.mydom.com are redirected to https://mydom.com . This is good.
My problem is at https://www.mydom.com it is not redirected to https://mydom.com, but show the content from https://mydom.com
How I can redirect https://www.mydom.com to https://mydom.com?

Answer 1

Simply create a .htaccess file using vi command in the public_html folder or document root of your website. Add the code below in your .htacess file.
RewriteCond %{HTTP_HOST} ^www.mydom.com$
RewriteCond %{SERVER_PORT} ^443
RewriteRule ^(.*)$ https://mydom.com/$1 [R=301]
If you have an existing .htaccess file in the public_html folder, try to make a backup using the command below:
$ mv .htaccess .htaccess.bak
or
$ cp .htaccess .htaccess.bak
Hope this helps.

You can use multiple vhosts block
<VirtualHost _default_:443>
SSLEngine On
SSLCertificateFile /opt/ssl/new/mydom_com.crt
SSLCertificateKeyFile /opt/ssl/new/mydom_com.key
SSLCertificateChainFile /opt/ssl/new/mydom_com.ca-bundle
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
ServerName mydom.com
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:8080/test-1.0.0/
ProxyPassReverse / http://127.0.0.1:8080/test-1.0.0/
</VirtualHost>
<VirtualHost _default_:443>
SSLEngine On
SSLCertificateFile /opt/ssl/new/mydom_com.crt
SSLCertificateKeyFile /opt/ssl/new/mydom_com.key
SSLCertificateChainFile /opt/ssl/new/mydom_com.ca-bundle
BrowserMatch ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
ServerName www.mydom.com
Redirect permanent / https://mydom.com/
</VirtualHost>
The only thing you need make sure is that certificate is valid for both example.com and www.example.com, so that you don't get https exception before the redirect.
