Anonymous Proxy: The server tries to anonymizing the web surfing. Web Proxy Server: The proxy that is targeted to the world wide web is known as a web proxy server. Caching Proxy Server: Caching is servicing the request of clients with the help of saved contents from previous requests, without communicating with the specified server. Forced Proxy Server: It is a combination of Intercepting and non-intercepting policies. It is commonly used in businesses to prevent avoidance of acceptable use policy and ease of administration. 
Intercepting Proxy Server: It combines the proxy server with a gateway. Hostile Proxy: It is used to eavesdrop upon the data flow between the client machine and the web. Web demands are straightforwardly shipped off the intermediary paying little mind to the worker from where they started. Non-Transparent Proxy: It is an intermediary that alters the solicitation reaction to offer some extra types of assistance to the client. Transparent Proxy: It is a proxy server that does not modify the request or response beyond what is required for proxy authentication and identification. Split Proxy Server: It is implemented as two programs installed on two different computers. The following image shows the reverse proxy configuration. The most popular reverse proxies are Varnish and Squid. It validated and processes a transaction in such a way that the clients do not communicate directly. Reverse Proxy Server: It is a proxy server that is installed in the neighborhood of multiple other internal resources. The following image shows forward proxy configuration. It bypasses the firewall made by authorities. After collecting the data from the sites, it forwards the data to the internet users directly. An open or forward proxy server refers to those sorts of intermediaries that get demands from web clients and afterward peruse destinations to gather the mentioned information. Open or Forward Proxy Server: It is the most widely recognized type of intermediary worker that is gotten to by the customer. The other proxy server has its own feature and advantages. The two most common types of proxy servers are forward and reverse proxy servers. There are many types of proxy servers available. Therefore, it can be said that the proxy server acts as a client as well as the server. The proxy servers transfer the replies to the client and also being cached to them. If the requested data or page does not exist in the local cache, the proxy server forwards that request to the destination server. If the requested data or page already exists in the local cache, the proxy server itself provides the required retrieval to the client. The proxy server accepts the request from the client and produces a response based on the following conditions: The following figure depicts the mechanism of the proxy server. To speed up access to a resource through caching. To keep the system behind it anonymous. There are two main purposes of proxy server: The most important point about a proxy server is that it does not encrypt traffic. It collects and provides information related to user requests. It plays an intermediary role between users and targeted websites or servers. 
In other words, we can say that the proxy server allows us to access any websites with a different IP address. It separates the client system and web server from the global network. It works as a gateway between the end-user and the internet. The proxy server is a computer on the internet that accepts the incoming requests from the client and forwards those requests to the destination server. In this section, we will discuss what is a proxy server, its types, advantages, need, and working of proxy servers. It provides varying levels of functionality, security, and privacy that depend on the use case, needs, or policies of the company. We can achieve the same by using the proxy server. In such a scenario, the proxy server comes into existence. But sometimes, we want to access those websites or servers that are restricted and we do not want to show our identity (IP address). Similarly, the proxy server is a computer on the network that has its own IP address.
