It might be simpler to just write immediately when you set a param. It's simple and foolproof, and it's only a negative for performance if you normally set multiple params in a single request. If your ultimate goal is to fix performance on your servers, I'd recommend looking at using encrypted data in a cookie and ditching server-side session storage. - Perrin
