You're welcome! Just to make sure you understood what I was suggesting -
when you grab a login page, you often get a cookie (or several) with it.
That then gets posted back along with your userid/password. If you *don't*
hit the login page before trying the post, you don't have the cookie(s) and
it'll fail. Obviously if the server is broken, that's another issue
altogether.
