So I spent the last week getting Cross Domain Cookies working for WooCommerce and now for MarketPress. I was wrong about my initial thoughts that this would be needed to be performed via CORS or JSONP. I have it working on all major browsers: Safari, Chrome, IE.
If interested in having this built into Marketpress, please like this post and/or send some points. Lets see interest on getting this integrated into Marketpress (maybe I'm the only one that thinks its a pain in the ass to set up a SSL for each domain that wants to sell something via Stripe )
I have been told many times by some staff that this poses a security threat...but after much research....that's simply not true. Or if it is please advise me why!
