Edit Question
Title
Body
There are a lot of SO questions that seem to address variations of this question. But they tend to be complex regex answers and I am hoping I can find something simpler. Given location.host values of foo.mysite.com app.foo.mysite.com mysite.com How can I get the root domain mysite.com ? I could do something like finding the second to last . , but this seems ugly and wouldn't work for any TLD's like .co.uk . If jQuery has an object that contains this information I am happy to use it. My goal is to create cookies that exist across all subdomains. To do this I need to find .mysite.com . I'd prefer not to hardcode it.
