Saving state in an applet

I'd like to be able to save the current game (of chess) in my applet but I'm not sure on the easiest way. I could communicate to a database but this seems like overkill. I could call a local web page that perhaps stores the game but again this looks quite difficult.

Is there an easy way of writing a string (about 300 char length) to the browser and letting it return it when that user next goes to the page. Any ideas?

Check out the various *Stream* methods in AppletContext. I've heard people report mixed successes with this, though.

If the user's browser is running a Plug-In2 Architecture JRE, use the PersistenceService of the JNLP API.

Earlier JREs might store a cookie with the help of JS.

HTML 5 offers Local Storage.

A trusted applet can store the settings on the local file system.

Are these techniques common?
ie would most browsers support them?
What happens if they're not supported?

PS I don't have any control over user's browsers.

The answer to each question is 'it depends on the technique you are referring to'. I am not about to write a treaties covering all possibilities. Be more specific and put some research in, before I'll offer any more.

And that is a good thing. If web/server side developers start thinking they have any right or power to control the user or their browser, things go down hill rapidly.
