Suppose that the RTT delay between the client and server is 10 msecs; the time a server needs to transmit an object into its outgoing link is 1 msecs; and any other HTTP message not containing an object has a negligible (zero) transmission time. Suppose the client again makes 50 requests, one after the other. waiting for a reply to a request before sending the next request. origin server O 11 msec Question: Assume the client is using HTTP 1.1 and the IF-MODIFIED-SINCE header line. Assume 50% of the objects requested have NOT changed since the client downloaded them (before these 50 downloads are performed) O 525 me server transmission delay (msecs): 1 RTT delay (msecs): 10 O 501 sec O 1050 msec browser cache
