Redirect doesn't work with SSL

I change https in base_url config.php but still no change.
I don't know where to put this AllowOverride and what is the correct syntax
Currently in our ssl.config file I have

#<VirtualHost *:80>
#DocumentRoot /path/to/site/
#ServerName www.example.com
#Redirect permanent / https://www.example.com/
#</VirtualHost>

#<VirtualHost *:443>
#DocumentRoot /path/to/site/
#ServerName www.example.com
#SSLEngine on
#SSLCertificateFile /root/www_example_com.crt
#SSLCertificateKeyFile /root/www_example_com.key
#SSLCertificateChainFile /root/certificate.crt
#</VirtualHost>

Lines are commented because otherwise this website redirects to out other website.
