Answer 1

One way is using cookies.

Store the values in a cookie, and read them back with javascript when the user hits the back button.

Or use the querystring like @Danny says. Why didn't I think of that right away :)

Answer 2

You should put the filters in the query string because:

(1)It's not secret data.

(2)When user click "back" button of the browser, of course he wants the list is well-filtered, instead of that he need to filter the list again. Also sometimes he may copy the url in the address bar and sent it to others.

Format the filters' info in a proper way, e.g. "filter1=name&filter2=price", and deal with the query string in Page_Load if there is a filter.
