What are the differences between GET and POST methods when sending requests in a browser?

GET and POST are two main methods of sending HTTP requests from a browser.

• GET is used to request data from a server. Parameters are passed in the URL (query string), which limits their size and makes requests cacheable and bookmarkable. GET requests should be idempotent (not change server state).

• POST is used to send data to a server, for example, when submitting forms. Data is sent in the request body, allowing larger volumes of data to be transmitted more securely. POST requests can modify server state.

Example:

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

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