is anyone aware of a client-side form persistence library?
Typically implemented on top of cookies, used along the lines
of "peristForm("myForm","myCookie",numDays)" or somesuch.
Then the cookie can be used onLoad in order to restore the
form's last content.

I imagine it must be possible to iterate over the controls of
the form, serialize them as a concatenated string, then
persist that as a disk cookie.

Thanks for any hint,
