Hello,
You can just about put the EXE and web files anywhere you want on the machine.
Once, the server's port is opened to the outside world, all you have to do is point at the IP address to that machine.
So, if your server is running at
http://123.23.45.67 , just add the port number: (say you're using 80) it would look like this
http://123.23.45.67:80. You do not have to specify anything else.
Now, you may not want to give your users an IP address. If you have a domain name, just "forward" the domain to your IP address.
It's actually the easiest web server to deploy that I have ever worked with.
Good luck and it's good to see you over here. (I can't remember your name but I know we have emailed each other before...)
