What exactly is RESTful programming?

Question

What exactly is RESTful programming?

Answer 1

This is what it might look like.

Create a user with three properties:

POST /user
fname=John&lname=Doe&age=25

The server responds:

200 OK
Location: /user/123

In the future, you can then retrieve the user information:

GET /user/123

The server responds:

200 OK
JohnDoe25

To modify the record (lname and age will remain unchanged):

PATCH /user/123
fname=Johnny

To update the record (and consequently lname and age will be NULL):

PUT /user/123
fname=Johnny
