How to store session variables between visits?

My website gathers some data on its first page, which is used on other
pages. I would like to 'store' the data in some session variables between
visits, to prevent any problems that may occur if a visitor bookmarks a
different page.

What is the best way of achieving this? Can I store the values in a cookie
on the clients pc?

Thanks for any help given
