Question One
Content proxy is a web service on your server that can fetch data from external
URLs and return it to the browser. How does the proxy improve the load time
for users?
Answer:-
A proxy server performs as an entrance between the internet and the user. It
deliver varying stages of safety, functionality, and confidentiality, depending on the user
use case, requirements, or business strategy (Sathiyamoorthi 2016). If the user is
applying a proxy server, internet traffic runs over the proxy server on its technique to
the location they demanded. It is an intermediate server splitting end operators from the
websites they use. The appeal then comes back over that same proxy server. Then it
forwards the documents received from the webpages to the user.
A proper proxy server possesses operators and the internal network sheltered
from the corrupt material that exists out in the rough internet (Aghaei-Foroushani and
Zincir-Heywood 2015). Finally, proxy servers can deliver an exceptional level of
confidentiality. It is essentially a processer on the internet with its protocol address that
the user processor identifies. When the user sends a web invitation, user appeal drives
to the proxy server rapidly. These server then creates user website requests on the user's
behalf. It also gathers the reply from the website server, and onwards user the website
page documents so people can observe the browser page.

Pg. 02 Question One
There are some categories of miss requests such as bad or good miss. Good
desires will cause the proxy to save copies of the miss substances, and the copies will be
retrieved again when demanded by customers in the upcoming (Sysel and Doležal 2014).
Wrong demands are those appeals that to root the proxy to save copies of the miss
entities, but the copy will not be retrieved again earlier. It is emitting from the cache.
The server might be the most straightforward method for developing the presentation of
Web-based structure by keeping Web objects. The web objects are expecting to be
applied again when demanded in the upcoming location nearer to the Internet operator.
It is positioning between the users and the internet that act to deliver facilities between
the Internet and users. It is decreasing the number of requirements sent through the
Internet to unusual servers.
