HTTP Performance with a local web cache. Now suppose that a web cache is added the lower network, as shown in the figure below, but that in all other aspects the network below is the same as the network above. All HTTP requests are first directed to the local web cache. You can assume that the delays $($both propagation delays and any transmission delays between the cache and a client are zero, since both are resident in the same network$).$ The client's browser cache is empty.
