Those pages/page are testing for javascript and setting a cookie or simply using javascript to set the cookie. Either way no JS no cookie... no cookie no page of interest.

the simple thing to do is go to one of these 'access' pages, view the source and see what cookie is being set. then in your LWP script put the discovered cookie into your cookie jar.

This is a fairly common practice but there are methods that are more complicated but can still be worked around. Try this way and let us know.

Oh yea and don't forget to thank dws. Since all I did was shout his answer back at you :)
