Instructions on using domain mapping with SSL (HTTPS://)

Hi,
So I splashed out and bought an SSL cert for my network. It is installed fine, but I am wondering how do I make this work with Domain Mapping?

Currently you can visit my network at http://domain.com, but my goal is to use https://domain.com so that it is all secure :slight_smile:

Any ideas on how to do this? Specific instructions or links would be helpful.

My host (hostGator) gave me this for my .htaccess file, but I'm not keen to try it without some better guidence:

# Force secure connection (SSL )
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://domain.com/$1 [R=301,L]

ALSO, how will having a network with https:// effect the sub-directory sites? Will the also be https;//, or not?

Thanks
