I need to write a app that will be on a pc on the internet, behind a
firewall. This app jobs is to listen to port 80 (because its the only open
port) and a ipaddress for a set of special chars (that I define). When it
receives those special chars I want to send it my ip and port so it can tell
my other program (which I already have) to connect back to me.
Can I use port 80 ?
Will it cause any problems with the browser ?
What components should I use ?
