Java Menu Question

I have a menu system on my page that expands and contracts when you click on it. I want to avoid using frames at all costs, but what I need is for the menu to remember its settings after you navigate to another page. For example, when I expand HEADING_1 and click SUBHEADING_1 it takes me to the page linked to SUBHEADING_1, reloads the menu with everything collapsed. What I want is for HEADING_1 to still be expanded. I am using an included ASP file for the menu so as not to have to change it foreach page in the site. Any help is greatly appreciated.
