Detailed explanation-1: -Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet.
Detailed explanation-2: -A proxy server, also known as a “proxy” or “application-level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the internet. Proxy servers provide increased performance and security.
Detailed explanation-3: -There are two types of proxies: forward proxies (or tunnel, or gateway) and reverse proxies (used to control and protect access to a server for load-balancing, authentication, decryption or caching).
Detailed explanation-4: -A proxy server lessens network traffic by rejecting unwanted requests, forwarding requests to balance and optimize server workload, and fulfilling requests by serving data from cache rather than unnecessarily contacting the true destination server. HTTP Server has proxy server capabilities built in.
