What HTTP ports can I use?
There are actually 3 HTTP alternative ports: 591, 8008 and 8080. They are assigned by IANA as “HTTP Alternate”, which makes them pretty much as official as it gets. If you run Linux as a non-privileged user (non-root) you can listen to any port above 1024, so 8008 and 8080 are good candidates.
How does the HTTP server know what port the port 80 is?
For example: the HTTP server knows that he’ll listen to connections that come in the port 80. And the server knows that anytime he receives some request on port 80, he’ll handle it to the http server.

What is port 8080 used for?
It manages all HTTP-based requests that originate from a computer, regardless of the number of requests and initiating Web clients. Similarly, the HTTP server responds to all requests received at port 80. Alternatively, HTTP may use port 8080, rather than port 80, typically to deploy a caching or proxy server.
