[2008] Creating a history for a web browser - what do I filter out?

Hey, I'm creating a history for my web browser, but what exactly do I filter out of it, every time I click something that changes the URL, say a submit button, it will add that to the history...?

I'm not sure what should be included in the history, obviously the site you visit, but it shouldn't duplicate (I can fix that I think), nor should it show the URL that changes each time you click a button.. for example a game, every time I click the attack button, added to the history is http://www.gamename.com\somethingelse.php etc...

Right now, I'm storing the history by date (I create a file with the current date), then in the WebBrowser_Navigated event, I add to that file the new address you've navigated too..

Does anyone know what I should do about this?

I don't know how to make it look like Mozilla\Internet Explorer's history, I might even be over doing and removing things from the navigation history that I shouldn't.
