You can store an *arbitrary* string in a cookie (note that there are usually rather tight limits regarding the size of all cookies of a domain, though). You could store a JSON string inside the cookie, or use multiple cookies. However, that wouldn't appear to solve your issue. It seems to me that the problem is: "how will the server be able to differentiate". Why should the server differentiate which tab made the request, at all? -- Christoph M. Becker
