  I doubt that lynx will be able to show such documents. It's said that 
user must login to Authentica before viewing - I guess some Java or Javascript
code forces to do this, and the information to show is encrypted in some way.
After logging in, some key is fetched to decrypt the document. Again, some
java or javascript code will force to abandon the document being viewed when
time limit expires.
