The proxy service can be organized in different ways, it depends on the principle of operation of this software intermediary. Let's consider the most common proxy options currently used in practice.

Forward Proxy – direct server: is located between data consumers and their external sources. Forward Proxy receives a request from the user, processes it using software algorithms, and only then goes to the external network. Using a direct proxy server, you can visit sites that are closed in your region, provide anonymous surfing on the network, etc. This type of proxy is the predominant option among such solutions.

Reverse proxy – reverse server: Most resources store information on several servers at once. The task of the reverse proxy server is to receive incoming requests, analyze them and redirect them to the desired resource. This option balances the load well, distributing traffic, especially during peak hours. When visiting a site, its visitors do not suspect that Reverse proxy is actively involved in this process.

Proxy servers provide anonymity on the network for their clients, but they differ in the degree of data confidentiality. There are several proxy gradations:

🔒 Transparent proxy server. The addressee can see the IP of the server sending the requests, and it is also clear that the request is made through an intermediary. The usual option for use in enterprises, universities, etc .
🔒 Anonymous proxy server. It changes the AI, so it provides anonymity for its client. With its help, you can bypass the blocking of various resources, negate the possibility of tracking by marketing robots. But the addressee resource in this case still understands that an intermediary service is accessing it, and not a real user.
🔒 Distorting proxy server. In this variant, both IP and HTTP headers change, which allows you to simulate a request from a real client, and not through proxy mediation.
🔒 Proxy servers with increased anonymity. These are the safest and most modern versions of this service. In the process of use, there is a frequent change of the user's IP address, it is quite difficult to track the user's real location.
