HTTP & HTTPS Protocols

HTTP (HyperText Transfer Protocol) is the foundation of data communication on the web.

What is HTTP?

HTTP is a request-response protocol. When you visit a website:

1. Your browser sends an HTTP request
2. The server processes it
3. The server sends back an HTTP response

HTTP Methods

GET    - Retrieve data (loading a page)
POST   - Send data (submitting a form)
PUT    - Update data
DELETE - Remove data

HTTPS - The Secure Version

HTTPS adds encryption using SSL/TLS:

• Data is encrypted in transit
• Prevents eavesdropping
• Verifies website identity
• Required for sensitive data

Important: Always use HTTPS for websites handling passwords, payments, or personal data.
