How do I make the Http protocol use a port other than 80?

you can use a different protocol on IE by appending the http port number to the domain name i.e. http://www.linkme.com.au:8273 would use HTTP on port 8273. If you are serving pages, you can do that via the settings in your web server. How to do that will vary between products. If you want it to be a permanent change you can use port forwarding on a tunnel, or use a proxy. Question: Why do you want to do that? The whole point of the use of port 80 is that it is a standardised port, if you try to connect on any other port you won't get access to much. If you are having porblems with port 80 being blocked by a firewall or by admin settings on your machine, then consult your admin people, or learn about SSH and tunnelling
