How to find out the listening port of a Web Server ?

Question

Hi,

There is a requirement to find out whether Port 80 and Port 443 is listening from a Web Server.

May I ask if I use http and https to that web site and there is response, does it mean that these 2 ports are listening ?
Is there any other tools we should use (Like: netstat) ?

Besides, according to developer, the web page makes use of Port 8080
https://server1.company.com:8010/mobile/#/main

May I ask

1. Is it a redirect to Port 8080 ?
2. Both Port 8080 and 443 listening ?

Thanks

1) Is it a redirect to Port 8080?

No, what port you specify in the URL is what port.

Both Port 8080 and 443 listening?

No, SSL is in no way tied to a single port value, you can use any port, provided that you specify it in the URL.
