We use Magento long time ago.
1.) We have a multi-store setup with 2 different domains. ( domainA and domainB )
2.) Our checkout page is located in domainB, we transfer customers with session id "SID" in the link from domainA to domainB.
3.) We use Magento 126.96.36.199 and share the cart content between the 2 stores with this method: [url removed, login to view]
We would like to update to Magento 1.9.1 , - We already tested it - but it seems this method is not working anymore to share the cart content between the 2 domains. Now the domainB is redirect to "Empty cart" and make a new session (SID).
I need the code which makes to share the cart content between the 2 stores.
I think the link above (with the original method for 188.8.131.52) is a big help to start and it's only an 1-2 hour work for a programmer who know Magento 1.9.1...
