 |

My site example.com has an SSL certificate for example.com and www.example.com and 000-default.conf file is set like this:
| Code: |
<VirtualHost *:80>
ServerAdmin admin@example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com
Redirect / https://www.example.com/
</VirtualHost>
<VirtualHost *:443>
ServerAdmin admin@example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com
SSLEngine on
SSLCertificateKeyFile /SSL/MyServer.key
SSLCertificateFile /SSL/www_example_com.crt
SSLCertificateChainFile /SSL/My_CA_Bundle.ca-bundle
</VirtualHost>
|
That is working fine, but I have a problem with subdomain sub.example.com
When you enter in browser https://sub.example.com you get warning about invalid certificate.
I want to ban access to https://sub.example.com and only allow http://sub.example.com
How to do that?
Current sub.example.com.conf file looks like this:
| Code: |
<VirtualHost *:80>
ServerAdmin admin@example.com
ServerName sub.example.com
ServerAlias sub.example.com
DocumentRoot /var/www/sub.example.com
</VirtualHost>

You can't control what URL users put in their browser, and browsers now default to https over http, so as described believe your site is going to get hit with requests for https://sub.example.com.
So the obvious question is why not set up a further secure virtual host for https://sub.example.com (using a SAN entry for the subdomain in your site certificate).
If you really have to serve non-secure content via http://sub.example.com, then you could always redirect from the secure virtual host to the non-secure one, unintuitive as that seems. |
