C++ Programming on Linux - Libevent Bufferevent Proxy Concept

In this short video, it will discuss another very important concept proxy. Talking about network or network applications, it's very often to hear the word proxy, especially in today's digital architecture, proxy server/proxy service are played very important role and widely be used in may application. There are many web pages and easy to find what is proxy and how it works on internet. In general, without using proxy, user send request to end point directly over network, and destination server will respond back directly to user side.

A proxy service is an intermediary role played by software or a dedicated computer system between an endpoint device and a client end. proxy concept, not limited for write a proxy server, in many applications, proxy concept is embedment as proxy object and provide customized proxy services to help API improve security, filter against malware and other cyber threats, log network traffic help analyzing network usages and redirect network traffic to improve load balance and network performance, especially for cloud or cluster based architecture.
