Redirect your visitors to SSL webpage!

After we've been able to get a free SSL certificate for our page now, we need to redirect to the SSL page.
According to Apache, the best way is to avoid using mod_rewrite !
Example:

< VirtualHost *:80 >
ServerName webmail.biotree.tk
Redirect "/" "https://webmail.biotree.tk/"
< /VirtualHost >
< VirtualHost *:443 >

ServerName webmail.biotree.tk

# ... SSL configuration goes here

< /VirtualHost >

I think this is the easiest way to redirect SSL from a non-SSL page.
