You could preserve web application state with JSON in URL like this:

  http://host/?state=[{id:1,selected=true},{id:2,selected=false}]

Is this preferable?

One motivation for doing something like this is if the user bookmarks the web page the web application state can be restored the next time the user visits the page.

    It might be doable, but I think it’s somewhat bad practice beacuse:

    • You are exposing a lot of technical details about your web app to the end users
    • Are you sure you’re using safe JSON parsing? Otherwise your opening your app up to Javascript injection attacks.
    • Sooner or later you’re bound to hit URL character encoding problems
    • Your URL’s not very descriptive (see http://css-tricks.com/guidelines-for-uri-design/ )

    My advice: create an ID for state bound to your JSON stored in a database (your URL’s would look more along the lines of http://host/?state=123 with 123 pointing to some kind of database record (not that it makes the URL’s very accessible either, but I still think it’s better due to the other points cited).
