A proxy server acts as a middleman that translates and evaluates request from clients to other network services. It is commonly used by network administrators to monitor the incoming traffics and contents to be served in the corporate network. In general, proxies can be classified into 2 groups, Forward Proxies and Reverse Proxies. Out of this two, Forward Proxies was the widely known proxies that have been sub-divided into few groups based on their implementation methods.
Forward proxies are usually working as a messenger between a private network and the public network, for example, Internet, to handle outbound requests. They are the common proxies that we use to isolate the private network from the public internet. They are often referred as mega proxies because they are able to manage a wide range of sources and high volumes of traffic. These proxies equipped with many features such as security, caching and web content filtering services, enabling network administrator to effectively manage and control the traffic flow through the proxies.
Reverse Proxies are generally used to process requests from the Internet through a firewall to isolated and private networks. In short, they serve as front line soldiers, providing a layer of security which prevents the clients from directly accessing the backend network (e.g. the contents server). In addition, reserve proxies also often used as the load balancers and cache servers, to optimize server accessing speed.
