What is the difference between HTTP and HTTPS?

HTTPS is HTTP with SSL/TLS encryption added. While HTTP transmits data in plain text (visible to anyone intercepting), HTTPS encrypts all communication. HTTPS is mandatory for any site handling sensitive data.

What does HTTP 404 mean?

HTTP 404 means 'Not Found' — the server couldn't locate the requested resource. This typically happens when a page has been deleted or the URL is incorrect.

Is HTTP still used today?

HTTP is largely replaced by HTTPS for public websites. However, HTTP is still used on private/local networks where encryption isn't needed. Most browsers now automatically upgrade HTTP requests to HTTPS.

What is HTTP?

HyperText Transfer Protocol (HTTP) was designed by Tim Berners-Lee in 1989 alongside HTML and the URL system — forming the three pillars of the World Wide Web. Every time you visit a website, your browser uses HTTP (or HTTPS) to request and receive web pages.

HTTP is a stateless, application-layer protocol — meaning each request is independent, and the server doesn't remember previous requests by default.

How HTTP Works

You Enter a URL

You type a URL like http://example.com in your browser and press Enter.

Browser Sends a Request

Your browser creates an HTTP Request with a method (GET, POST, etc.), headers, and optional body — sent to the web server.

Server Processes the Request

The web server receives the request, finds the resource (HTML page, image, API data), and prepares a response.

Server Sends a Response

The server replies with an HTTP Response containing a status code (200 OK, 404 Not Found), headers, and the requested content.

Browser Renders the Page

Your browser reads the HTML and renders the webpage visually.

HTTP Methods

Method	Purpose	Example
GET	Retrieve data	Loading a webpage
POST	Send data to server	Submitting a form
PUT	Update existing data	Editing a profile
DELETE	Remove data	Deleting a post
PATCH	Partial update	Changing just a username
HEAD	Get headers only	Checking if resource exists

HTTP Status Codes

Code Range	Meaning	Common Examples
1xx	Informational	100 Continue
2xx	Success	200 OK, 201 Created
3xx	Redirection	301 Moved, 302 Found
4xx	Client Error	404 Not Found, 403 Forbidden
5xx	Server Error	500 Internal Server Error

HTTP vs HTTPS

Feature	HTTP	HTTPS
Full Form	HyperText Transfer Protocol	HTTP Secure
Port	80	443
Encryption	❌ None	✅ SSL/TLS
Data Safety	❌ Visible to hackers	✅ Encrypted in transit
Google Ranking	❌ Penalized	✅ Preferred
Browser indicator	⚠️ "Not Secure"	🔒 Padlock icon

Always use HTTPS for websites that handle logins, payments, or any personal data. Google Chrome marks all HTTP sites as "Not Secure."

HTTP Versions

Version	Year	Key Feature
HTTP/1.0	1996	One request per connection
HTTP/1.1	1997	Persistent connections
HTTP/2	2015	Multiplexing, header compression, faster
HTTP/3	2022	Built on QUIC (UDP), even faster
