I was wondering if anyone knows whether there is a maximum size limit on a cookie content
1) Is this a limit per cookie in a single domain? i.e. no single cookie value can exceed XX bytes
2) Is this a limit on all the cookies that get saved under a single domain? i.e. the total size of all the cookies cannot exceed XX bytes
3) Is the limit different from browser to browser?
4) How can I detect what the limit is?
Your best solution if you need more than 4k would be to use sessions and just save an identifier in the cookie. Sessions allow for a lot more information than cookies do they just don't allow you to save anything between browser sessions so you will need to save the session data in a file or database and use the cookie to identify which data to retrieve to set up the session for the next visit.
