Is it possible to use the GET method to send data to the server?

Yes, the GET method can be used to send data to the server, but with limitations.

GET requests transmit data via the URL as query parameters, for example:

GET /search?q=example HTTP/1.1

However:

• The amount of data is limited by the URL length (usually around 2000 characters, depending on the browser and server).
• Data is visible in the address bar, which is not suitable for confidential information.
• GET requests should be idempotent and not change the server state.

For sending large amounts of data or sensitive information, POST or other methods are usually used.

In Node.js, for example, to handle GET requests with parameters, you can use req.query.
