I've seen this before !
What you have to do is make sure every significant state can somewhat get back to the server on the next request.
For user-login you have the cookie.
For specific editing context information, you can get some back in having eo-id encoded within the form. Like having a text field with a name = 'Book_01_title' that way, you could deduce that you have a text-field on the title attribute of an eo of entity Book with 1 as the primary key.
For persistency and be session independent, you have to make every action a direct-action and not require a session. You have to see Session as optional and not rely on it, just consider it as a cache that can boost request evaluation
So with a combination of cookies, direct-action and special form encoded name you could reconstitute most (if not all) of your context.
In fact I do not remember the implementation, but it must resemble what I just described.
It was presented to me in 2000, it was a WO engineer that developed it for a client, and he showed us his application running, went to a form page, started to fill it and then stopped the application and restarted it (so obviously session id was no longer valid), he then submitted the form and the client did go along as if nothing happened server side. You can now imagine a farm of wo apps, if one of the instance goes down, no worries, another one will take the request and respond.
