Question. $5$

Suppose within your Web browser you submit a URL to obtain a web page. Assume the following:

The local proxy server $($web cache$)$ is used, and currently has no established TCP comnections

with the client or any server.

Your web browser is configured to use the local proxy server for all web requests.

Your web browser does not have the IP address of the local proxy server but the IP is cached in

the local DNS server.

The base$-$HTML$.$ file is hosted by Onigin Server $1$ and references two $(2)$ other objects. The first

object resides in Origin Server $1,$ while the second resides in Origin Server $2.$

The local proxy has a fresh and up$-$to$-$date cached copy of the base$-$HTML file. However, The

two referenced objects are not cacthed at the local proxy.

The local proxy knows the IP addresses of Origin Server $1$ and Origin Server $2.$

Persistent HTTP without pipelining is used.

Utilizing the diagram below, use labeled arrows to show the complete sequence of messages from the

moment your Web browser requests the web page until the indexed objects in the hase$-$HTML$.$ file are

received by your Web browser.

$($note that the names of possible message that can be used are TCP$-$connect$-$reyuest, TCP$-$conuect$-$

granted, HTTP$-$request, HTTP$-$reoponse, DNS$-$query, DNS$-$response$)$
