What is HTTP?
The following information is featured on the homepage in the main site:
However, this is not a very detailed definition. Look here for much more information. First of all, although HTTP is on port 80 as a standard, it can be on other ports that are open. However, be warned, as some of these ports are standards for other protocols.
However, if you use a port that is not being used for one of these purposes, take port 1209, you can’t just type the domain name, example.com. One has to type example.com:1209 for it to work.
