How does IW2000 communicate with the browser?

IW2000 acts as a local Proxy server between the browser and the Internet.

A Proxy server is a program that receives informations or requests from another program and sends them to a third one.
IW2000 receives the requests sent by the Web browser and transmits them to the Internet (or to the Proxy server) and vice versa.

IW2000 permanently controls the port "8080" in order to receive the requests coming from the Web browser and in return to send them to the port "80".
