Hi,
I was wondering if someone can explain me what do the following lines mean in plain english.
The GET method should be safe, that is, without any side effects for which
users are held responsible. For example, most form queries have no side
effects. If a client request is intended to change stored data, the request
should use some other HTTP method.
The GET method should also be idempotent, meaning that it can be safely
repeated. Sometimes making a method safe also makes it idempotent. For example, repeating queries is both safe and idempotent, but buying a product
online or modifying data is neither safe nor idempotent.side effects for which users are held responsible
