You shouldn't need to worry re POST and GET.

Visiting the login page is presumably not enough in itself to log you
in.  So, what are you doing to ensure you're logged in?

Probably you want to fill in and submit the login form on the login
page.  Alternatively, use e.g. mechanize.MozillaCookieJar and load
cookies from your web browser (this option requires that you are
already logged in persistently, though, so I'd suggest filling in the
login form as the safe option).
