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 |
