How can I set up SSL login authentication on one domainfor multiple domains

#1 08-22-2008, 12:02 PM

Our site currently runs in 22 countries with 22 different country domains:

www.mysite.com
www.mysite.co.uk
www.mysite.fr
etc

We want to use SSL on our login pages but realise that the cost of
certification for every domain is expensive. One solution would be to channel
all login activity to a single domain, eg: www.mysite.com/login.cfm?site=fr
which would then redirect to www.mysite.fr ? this is how Google do it

But, currently we are using encrypted cookies for login authentication so we
would have the problem of having to transfer the cookie info across domains
securely. Is there any way of going about this?

Any other suggestions would be great, too. We do plan to move to session
management for logins but this is a longer term project so we are hoping to
sort out the SSL prior to that.

Can you not pass the values you need as URL parameters? Encrypt them befor you send them and then decrypt them on the new domain. Then add them to whatever place you need (cookie, session, etc.)?
