web browsing with clear text

[MP18]

when we say we access the website  with clear text does it mean port 80?

Hello @MP18,

It doesn't neceassarily means it is using port 80. Instead it means it is using HTTP protocol which is not encrypted. One can configure HTTP with custom port too. 

[MP18]

do you mean we can use http  on custom port 443?

[Rajesh12]

Yes, you can do that given that there is no HTTPS service running on port 443. Format of the URL to access will be as below.

<protocol>://Hostname(URL):<port_configured>

HTTP://xyz.com:443 - It is using HTTP protocol with custom port 443.

@MP18,

You can run any protocol on any port you wish, as long as the server and the client are actually configured to use the same port. You can technically run HTTPS over 80 if you wish, you would just have to specify https://<server>:80 since the browser will make an assumption that all https traffic would be going to port 443.
