GET is for fetching data, appending parameters in the URL, ideal for searches. POST, used for updates, sends data securely in the request body
Operation: GET Method: Used to retrieve information from the server. POST Method: Used to create or update a resource.
Data Location: GET Method: Appends data to the URL, visible to all.
POST Method: Includes data in the request body, not displayed in the URL.
Idempotency: GET Method: This is meant to be Idempotent, the same request can be repeated with no further changes, and should not have any affect on server state.
POST Method: Mostly this is Non-Idempotent since it might affect server state, but can also be idempotent in few cases based on server implementation.
Request Size : GET - Request sizes are usually small, since request data is mostly sent in url itself.
POST - Request size can vary. Maximum sizes can depend on permissible limits provided by the server. For ex - Apache can support a maximum limit of 2GB.
Caching: GET Method: Can be cached, leading to better performance.
POST Method: Not cached by default, as these are not idempotent in general.
Security: GET Method: Less secure as data is exposed in the URL.
POST Method: More secure; data is concealed within the request body.
