In particular, if you're following the approach Bernard suggests, you
can either:

1. Log in every time your program runs, by going through the sequence
   of clicks, pages, etc. that you would use in a browser to log in.

2. Once only (or once a month, or whatever), log in by hand using IE
   with a "Remember me"-style feature (if the website offers that) --
   where the webapp asks the browser to save the cookie rather than
   just keeping it in memory until you close your browser.  Then your
   program can load the cookies from your real browser's cookie store
   using this:

There are other alternatives too, but they depend on knowing a little
bit more about how cookies and web apps work, and may or may not work
depending on what exactly the server does.  I'm thinking specifically
here of saving *session* cookies (the kind that usually go away when
you close your browser) in a file -- but the server may not like them
when you send them back the next time, depending how much time has
elapsed since the last run.  Of course, you can always detect the
"need to login" condition, and react accordingly.
