Explain the differences between HTTP GET and POST methods in the context of data transmission to the server

The HTTP methods GET and POST differ in how they transmit data and their purpose:

• GET transmits data via the URL as query parameters. It is convenient for retrieving resources and requests that do not change the server state. Data is visible in the address bar, limited in length, and requests can be cached.

• POST transmits data in the request body, allowing for larger volumes and more sensitive information to be sent. It is used for creating or modifying resources on the server. Data is not displayed in the URL and is not cached by the browser by default.

Example of a GET request:

GET /search?q=python HTTP/1.1
Host: example.com

Example of a POST request:

POST /submit HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded

username=user&password=123
