HTTP defines how messages are formatted and transmitted, and what actions Web servers
and browsers should take in response to various commands.One of the most popular uses of the internet is to download/ upload files that is transfer files
from a computer on the internet to your computer and vise versa which is achieved through FTP
A proxy server that all computers on the local network have to go through before accessing information on the Internet.which improves the network performance and filter what users connected to the network can access.Proxy servers have two main purposes i.e improve performance and filter requests.Proxy servers dramatically increase the speed of the web-searching,performance,etc and also it takes off the load from the 'main'server.We must find new ways of improving the blocking of unauthorised sites and improve the performance so that it reduces cost while handling more data/information.a http proxy allows a user to change their IP online and remain completely anonymous. Using anything less than a HTTP based proxy server will either risk revealing your identity online or being unable to access many websites and their content.
