GET
and POST
stand as two fundamental verbs enabling web interactions. Understanding their differences is crucial for effective web development:
Operation
GET Method: Used to retrieve information from the server.
POST Method: Used to send data to the server to create/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: Idempotent; the same request can be repeated with no further changes.
POST Method: Non-idempotent; repeating the same request can lead to different results.
Data Size
GET Method: Limited by the URL length; less data can be sent.
POST Method: No limitations on data size; suitable for large amounts of data.
Caching
GET Method: Can be cached.
POST Method: Not cached by default.
Security
GET Method: Less secure as data is exposed in the URL.
POST Method: More secure; data is concealed within the request body.
