HTTP Response Status Codes

How communication happens between webserver and client-user
Usually only clients make HTTP requests, and only to servers. Servers respond to a client's HTTP request. A server can also populate data into a client cache, in advance of it being requested, through a mechanism called a server push.
When requesting a file via HTTP, clients must provide the file's URL.
The web server must answer every HTTP request, at least with an error message.

HTTPS - A secure version of HTTP

HTTP specifies how to transfer hypertext (linked web documents) between two computers.
