Live Preview in different languages on different top level domains Our website offers three different languages. Each language has it own top level domain (example: domain.de, domain.it, domain.fr). Everything works like it should, except the Live Preview function. We have already tryed the things described here: https://craftcms.com/support/cross-domain-live-preview and a few other tweeks we found in stackoverflow. Every solution we found, only works with subdomains.

As i understand, it's not possible because the browser does not allow cookies accross domains (Cross-Domain Policy). 

Does anyone have experience with handling various languages and top level domains in Craft CMS? How can we handle this requirement?
With the current implementation of Live Preview in Craft, using Live Preview across different top-level domains isn't possible due to the cross-domain policy (as you found out) along with a few others.

We've got a few ideas on how we might address this in the future, but it will definitely be after Craft 3 comes out.
