Download delays for 100 objects (HTTP 1.1 with local web caching). Consider  an HTTP 1.1 client and server. The RTT delay between the client and server is 2  seconds.

The client makes 100 requests one  after the other, waiting for a reply before sending the next request. All requests first go  to the cache (which also has a 2.0 sec. RTT delay to the server but zero RTT to the  client).  How much time elapses between the client transmitting the first request, and the receipt of the  last requested object, assuming no use of the IF-MODIFIED-SINCE header line anywhere, and  assuming that 50% of the objects requested are "hits" (found) in the local cache?  Your answer should be among the following list( 702 secs, 552 secs, 352 secs, 350 secs, 150 secs) .

Download delays for 100 objects (HTTP 1.1 with local web caching). Consider  an HTTP 1.1 client and server. The RTT delay between the client and server is 2  seconds. Suppose the time a server needs to transmit an object into its outgoing link is  3 seconds. 

There is also a local web cache, as shown in the figure below, with negligible (zero)  propagation delay and object transmission time. The client makes 100 requests one  after the other, waiting for a reply before sending the next request. All requests first go  to the cache (which also has a 2.0 sec. RTT delay to the server but zero RTT to the  client). 

How much time elapses between the client transmitting the first request, and the receipt of the  last requested object, assuming no use of the IF-MODIFIED-SINCE header line anywhere, and  assuming that 50% of the objects requested are "hits" (found) in the local cache? 

Your answer should be among the following list( 702 secs, 552 secs, 352 secs, 350 secs, 150 secs) . Show your work/Explain your answer
