i was reading as below

what is the meaning of below

Consider the following URL −


If you hit the above url using your browser or using a java based client or using Postman, result will always be the User XML whose Id is 1 because the server does not store any information about the client.


how result with id 1 is related to statelessness.

since we created new user it created with id 1 and while retrieving we get same value right.

please advise
