I have a multi-page site that I want to be able to resume at the same
page if the user leaves and comes back later (say, days later). I'm
thinking that I'll set a cookie as each page is displayed and when the
main/first page displays, I'll look for the cookie and open the page it
names. If a new version of the site omits a page that used to exist or
if the cookie somehow becomes corrupt, I don't want to display an error
when I try to open the page. Can I check for the existence of page
(CGI file) from JavaScript so I don't try to display the page if it
won't be found?
