Cross domain tracking - Are there any ways to persist certain data source setting across a domain? Can base variables be used for this? I have site abc.com where I set a visitorID and that user clicks over to my other site def.com I want visitorID to

come over to site def.com. Using query parameters is not currently an option. Query parameters require a change to our SAML process and we are looking at 12-16 months for that to get pushed through the queue.

Without shared authentication (like a Google account sign in) between sites, I'm not sure how else you can persist data between two separate domains without appending query string parameters. Someone else might have a better idea though.
