passing data between web forms and between html pages

Question

i have two web forms pages.
how do i append values to the querystring in the first page, and then extract them on the second page?
i know its easy to pass values in web form pages using properties, but i want to do it using the query string appended to the URL. i want to know how to pass values in from one html page to another and then display the 2nd page. thanks for any help
