passing values from a web page into windows form application

Hi guys,

How can I pass session/application values from a web page (ASP or
ASP.NET) that is on a host company, into my cliente application?

So I can hide menus based on access permisions once the user makes the
log in in the web page by the application.

I'm using VB.NET with Web Control COM


Thank you
