I use hidden form field, they don't want me to use cookies.

You're hosed if you expect forms to repost on refresh. You either need to embed the session ID in the URL, or convince "them" to let you use cookies.

If you're sure than none of your clients are sitting behind any sort of network address translation (NAT), then you might be able to keep track of session on the server side, by associating them with the client's IP address.
