I am creating an e-commerce platform and will allow hosting of e-commerce pages using CNAME records for store domain and an ssl certificate page on another domain for the sector checkout page. Both the domains below will reside on my server pointing to same code base.
Here is an example: http://store.mystore.com
https://checkout.phpppointofsale.com/checkout?domain=store.mystore.com
Is the only real way to not using session data for checkout process and pull from a database instead? Or use database driven sessions and look up the data that way?
