Hmmm,
It is going to be difficult then. I can think of two things (I may be wrong totally):

1) See if adding cookies to the user agent solves it. You can use HTTP::Cookies
2)Try to make your useragent appear as IE or Firefox. I am not sure if it legal. Sincere apologies if it is illegal. Don't try until you figure that out. Regarding how to do it it should be something like,
$ua->agent("Mozilla/4.76 [en] (Windows NT 5.0; U)");

That is all that comes to my mind. Monks can any one help us on this.
