## default-ssl.conf
Now, edit the file `/etc/apache2/sites-available/default-ssl.conf`, remove everything and, again, add each rule while modifying the relevant fields:
This ruleset will redirect all clients that specify an unknown `Host` to the domain of our choice. I recommend you uncomment the `ErrorLog` directive while setting things up in case a problem occurs with PHP. Don't worry about the invalid SSL paths, we will generate our certificates later; Just make sure you specify the right domains in there:
First, append the following redirect rule to point traffic from `www.4get.ca` to `4get.ca`:
```xml
<VirtualHost *:443>
ServerName www.4get.ca
SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/4get.ca/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/4get.ca/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/4get.ca/chain.pem
RedirectMatch 301 ^(.*)$ https://4get.ca$1
</VirtualHost>
```
This ruleset tells apache2 where 4get is located (`/var/www/4get`), ensures that `4get.ca/settings` resolves to `4get.ca/settings.php` internally and that we deny access to `/data/*`, which may contain files you might want to keep private. `StdEnvVArs+` will make it so that PHP can view if the connection uses HTTPS, and which cipher was used. Useful for basic bot protection.
Make sure to replace `4get.ca` with your own domain under the `SSLCertificate*` directives!

Don't forget to specify your other services here! Here's an example of a ruleset I use for `lolcat.ca`:
```xml
<VirtualHost *:443>
ServerName lolcat.ca
DocumentRoot /var/www/lolcat
Options +MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

```
... Alongside with it's redirect rules.
```xml
<VirtualHost *:443>
ServerName www.lolcat.ca
RedirectMatch 301 ^(.*)$ https://lolcat.ca$1
</VirtualHost>
```
By default, the first rule dictates where traffic should be redirected to in case the client specifies an unknown domain name. Don't forget your webserver's other rules!
