Long description

The figure shows 3 browser windows and a server that illustrates two scenarios. In the first scenario, the first browser window labeled User X makes two H T T P requests to the server using the GET method for index dot P H P and order dot P H P. In the second scenario, the second browser labeled User X makes an H T T P request for index dot P H P using the GET method and the third browser labeled User Y makes an H T T P request for order dot P H P using the GET method. Note: From the perspective of H T T P, these two scenarios are the same.
