Part 1. Starting with the basics.... (it does get more complex, a lot more complex, I assure you). In this blogcast, you see an overview of the infrastructure and browse the "emulated" Internet using a client machine connected directly to the Internet. This client is move back to the corporate network and discover that Internet browsing no longer works.

<HR>
 


Welcome to Microsoft (www.microsoft.com)
<% response.write " The time is " & now() & " " %>
 

<%
response.write "You requested this page from " & request.servervariables("REMOTE_ADDR") & " "
if request.servervariables("REMOTE_ADDR") <> "72.16.8.252" then
response.write " You are directly connected to the INTERNET"
else
response.write " You are connected to the Corporate LAN"
end if
