How does HTTP work?
As a request-response protocol, HTTP gives users a way to interact with web resources such as HTML files by transmitting hypertext messages between clients and servers. HTTP clients generally use Transmission Control Protocol (TCP) connections to communicate with servers.
HTTP utilizes specific request methods in order to perform various tasks. All HTTP servers use the GET and HEAD methods, but not all support the rest of these request methods:
GET requests a specific resource in its entirety
HEAD requests a specific resource without the body content
POST adds content, messages, or data to a new page under an existing web resource
PUT directly modifies an existing web resource or creates a new URI if need be
DELETE gets rid of a specified resource
TRACE shows users any changes or additions made to a web resource
OPTIONS shows users which HTTP methods are available for a specific URL
CONNECT converts the request connection to a transparent TCP/IP tunnel
PATCH partially modifies a web resource
What is the process of HTTP?
A simple HTTP transaction is one where the client makes a single request for HTTP content. ... Send: Client sends the HTTP request to the web server. Wait: Client waits for the server to respond to the request. Web server processes the request, finds the resource, and sends the response to the Client.
What is HTTP in simple words?

How does a web request work?
The browser sends an HTTP request message to the server, asking it to send a copy of the website to the client (you go to the shop and order your goods). This message, and all other data sent between the client and the server, is sent across your internet connection using TCP/IP.
What is port number of HTTPS?
The SCI protocol uses only HTTPS to secure for the credentials passed in each request. By default, these two protocols are on their standard port number of 80 for HTTP and 443 for HTTPS.
