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

• A. GET requests submit data while POST requests retrieve it
• B. GET requests are faster than POST requests
• C. GET requests send data in the URL while POST requests send data in the body
• D. GET requests are secure while POST requests are not

Answer: (C)

The distinction between GET and POST requests is fundamental to understanding how data is transmitted over the web. GET requests are designed primarily for retrieving data from a server. When a GET request is made, any parameters being sent along with the request are appended to the URL in the form of a query string. This allows users to easily share URLs or bookmark them since the data is visible in the address bar.

On the other hand, POST requests are intended for sending data to the server, such as when submitting forms or uploading files. Unlike GET, which places data in the URL, POST requests encapsulate this information in the body of the request. This method allows for a larger amount of data to be sent in a more secure way, as it does not expose sensitive information in the URL.

This fundamental difference in how each request handles data transmission is crucial for web development, as it impacts both the use of resources and the security of user information. Understanding these differences helps developers choose the appropriate method depending on the nature of the data being transmitted and the required security measures.
