Hint: many web stacks suppport server-side sessions. Via cookies.

  Yeah, but you don't want to keep navigation state in the session. Otherwise you have to keep the session alive indefinitely to support bookmarking. Also, session based navigation state breaks if you browse the site in two tabs at the same time. And it breaks the back-button.

    pg's server-side closures are just a variation on the session theme, except that the data being stored is a procedure. You've just listed a bunch of flaws evident on this very forum . Any link with fnid as a parameter is pointing to a server-side session closure that might expire before you actually click the link.

      OK, agreed, I took your "hint" to indicate that you believed the problem could be solved by cookie-based sessions.
