I'm trying to implement a shopping cart, but the problem is that the web host uses shared SSL. So the user will be switching from domains when going from non-secure to a secure area:
http://www.mydomain.com/page1.php
to
https://www.webhostdomain/~myusername/page2.php
obviously the session cookie won't be valid across both domains, and i need to carry the session over. Does anyone now of a clean, neat way to do this?
