Is there a modern sessionStorage alternative that works across subdomains?
cookies, javascript, local-storage, session-storage
Solution
This is almost a hack, and its not secure but it's a neat trick never the less. JavaScript object window.name can hold strings of data and the data does persist even when loading a new page or switching domains. Check this SO about it here:

Problem
We recently switched from cookies to using sessionStorage - the trigger for switching was IE issues. Now, we're discovering that sessionStorage doesn't work across sub-domains - the storage of `www.site.com` is isolated from that of `site.com`. Is there a modern alternative to get the two to cooperate? This is easily accomplished by cookies, but I'd hate to revert from sessionStorage, or (gasp) use both methods concurrently.
