you would have to write a local js file with ActiveX file handlers and a filler for the form and then write someone on the address bar of IE like..
// Assuming that you create a "remeber values" thing yourself for a certain site...
javascript
:void(var blah = document.createElement("script");blah.src="c:\\yourscript.js"

;
// Or if you're the webmaster put that code in your <head> section...
Or if you wanted to get all complex with it and like, you could use a set of foreach loops and such and get all the forms and form elements into a file with the site that they are from. And have it bring that information back next time it comes... you can do alot of things... Sorry, i dont remember the ActiveX file handlers in JS (this will be IE only, i think) but you can check
www.webxpertz.net . They will probably have it.
-- Hope you understood that as i have a tendancy to ramble
