Why do you need cookie persistence? Is this a service with few clients, or where the majority is behind NAT addresses? Otherwise you might consider to persist on source IP?

 

If you have control over the client you might be able to ask the developers to add a custom header in the initial request, ie "Persist: [client hostname].

 

Or, and this is an ugly one (not for sensitive eyes), if you have no control over the client you might consider persisting on IP and user agent (concatenate them, make an md5/crc32 hash out of them). Then you might have a bit more spread between browser and browser versions at least.
