What is the main difference between GET and POST requests in HTTP?

• A. GET requests send data, while POST requests retrieve data
• B. GET requests modify data, while POST requests fetch data
• C. GET requests retrieve data, while POST requests send data for processing
• D. GET requests are secure, while POST requests are not

Answer: (C)

The main difference between GET and POST requests in HTTP lies in their purpose and how they handle data. GET requests are primarily designed to retrieve data from a server. When you use a GET request, the data is sent as part of the URL in the form of query parameters, which makes it easily visible and accessible. This makes GET suitable for requesting resources or data without causing any modifications on the server.

On the other hand, POST requests are intended for sending data to the server for processing. They allow the submission of data such as form submissions and file uploads, as the data is included in the body of the request rather than the URL. This not only allows for larger amounts of data to be sent but also makes it less visible to users, as it does not appear in the URL.

Understanding these differences is crucial for web development and API design, as it determines how data is transferred and how the server interprets those requests.
