Finally I set apache2 to get a single certificate for all subdomains.
[...]
# Go ahead and accept connections for these vhosts
# from non-SNI clients
SSLStrictSNIVHostCheck off
# Apache setup which will listen for and accept SSL connections on port 443.
Listen 443
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:443
# Because this virtual host is defined first, it will
# be used as the default if the hostname is not received
# in the SSL handshake, e.g. if the browser doesn't support
# SNI.
<VirtualHost *:443>
ServerName domain.localhost
DocumentRoot "/Users/<my_user_name>/Sites/domain/public"
<Directory "/Users/<my_user_name>/Sites/domain/public">
Order allow,deny
Allow from all
</Directory>
# SSL Configuration
SSLEngine on
...
</VirtualHost>
<VirtualHost *:443>
ServerName subdomain1.domain.localhost
DocumentRoot "/Users/<my_user_name>/Sites/subdomain1/public"
<Directory "/Users/<my_user_name>/Sites/subdomain1/public">
Order allow,deny
Allow from all
</Directory>
# SSL Configuration
SSLEngine on
...
</VirtualHost>
<VirtualHost *:443>
ServerName subdomain2.domain.localhost
DocumentRoot "/Users/<my_user_name>/Sites/subdomain2/public"
<Directory "/Users/<my_user_name>/Sites/subdomain2/public">
Order allow,deny
Allow from all
</Directory>
# SSL Configuration
SSLEngine on
...
</VirtualHost>
So, for example, I can correctly access
https://subdomain1.domain.localhost
https://subdomain2.domain.localhost
...
Now, anyway, I have problems on accessing
http://subdomain1.domain.localhost
http://subdomain2.domain.localhost
...
Since I use a Mac Os, on accessing the "http: version", I get a default page "Your website." (instead of a error). Why does it happen?
