You can use the hash URL (search # price = 100) using the window.location.hash methods. They will receive bookmarks, and the user will be able to navigate through them using the back and forward buttons.
Usage example:
<a href="#">100</a> $('a').click(function() { window.location.hash = 'price='+$(this).html(); return false; });
Sets the URL search#price=100 without updating.
