Unfortunately you are not posting in customer service so there is no escalation.  You need to contact the website owners for information on access issues.
Your script does not help any because your issue is with header.  The site will tell you which headers you need to allow access.  It is likely you are not authenticated for the kind of access you are asking for.
Try also poting in the IIS forum or the forum for your web server.  This forum is for admin scripting of Windows and not for general web scripting.
