"proxy" refers to a software "proxy" refers to a proxy often called proxy server software that serves as an intermediary between client and server via the internet. Without the use of a proxy, users could make a request for an item directly to a server, and the server would serve an item directly for the client. Although this method is easy to comprehend and use, proxies can provide benefits such as increased performance, privacy and security, and so on. As a layer of pass-through, the proxy functions as a guardian to the internet between users and servers.

In general, the system of server hardware that is paired with the software to install proxy servers is often referred to as proxy servers. This article will concentrate on proxy servers which are generally classified as software, and specifically, in relation to web servers. We will provide a brief overview of the two primary types of proxies: that is forward proxy and reverse proxy. forward proxy and reverse proxy. reverse proxy. Each type comes with its own application scenario, which is often misunderstood due to the overlapping terms.

This article will give you an understanding of nature of proxies, as well as their subtypes and ways in which they can be beneficial in a range of configurations. If you go through this article, you'll discover situations where the use of proxies is beneficial and identify the best option between forward proxy and reverse proxy for a particular scenario.

Understanding Forward Proxies

A forward proxy, also known by the name of an open proxy serves as the representative of the client trying to transmit an internet request to an source server. In this scenario, every attempt to send requests by the user will be sent via forward proxy. This forward proxy acting in the place of the client will review the request. Then, it will determine whether or not the client is able to send requests via this particular forward proxy. Then, it will decide whether to reject the request or forward it to the source server. The client isn't able to establish a direct connection with the Internet. It can only connect to the internet that forward proxy allows it to connect to.

The most popular reason to utilize forward proxy servers is to increase privacy or security while using the internet. A forward proxy can be used to connect to the internet instead of a client, and in this way, it utilizes a different IP address than the IP address used by the client.

Depending on how it's been setup, and based on the way it's set up forward proxy could provide a variety of functions and allow users to:

  • Beware of Ad-trackers.

  • Circumvent surveillance.

  • You can identify restrictions based on your geographical area.

Forward proxies can also be used for security systems that are centralized and access dependent on permissions, for instance at work. In the event that all internet traffic flows through an open forward proxy layer, an administrator can restrict access to only a select group of internet users, which is filtered by a common firewall. Instead of creating security firewalls on the layer that is used by clients that can be utilized by a number of computers that have different kinds of environments, there is a way to establish a firewall located at the front proxy layer.

Be aware that forward proxy servers require manual configuration for use before they can be utilized, whereas reverse proxy servers can be obfuscated by clients. Based on the fact that the IP address of a user is relayed to the server that originated it by the forward proxy, privacy and anonymity can be granted or denied.

There are a variety of options to consider for forward proxy services.

  • Apache An open source, well-known web server that has forward proxy capabilities.

  • Nginx: Another widely used open-source webserver that includes forward proxy features.

  • Squid: A free forward proxy that works with the HTTP protocol. It's not included with the whole web server. Follow our steps on how to configure Squid proxy to permit private connections on Ubuntu 20.04.

  • Dante Forward proxy that utilizes the SOCKS protocol instead of HTTP which is more appropriate for situations such as peer-to-peer connections. You may also want to know how to set up Dante proxy to permit private connections on Ubuntu 20.04

Understanding Reverse Proxies

A reverse proxy functions in the capacity of an intermediary for web server, that handles customer requests on behalf of. It could represent a single, or multiple servers. Additionally, it could serve as an app server like Gunicorn. In either case, a request would come through the internet generally. The request is typically sent directly to the web server that hosts the resources that the client requires of. In contrast, a reverse proxy acts as an intermediary that isolates Web servers from any direct contact with the web's public.

From the perspective from the client's viewpoint the procedure of using reverse proxy is not different from interacting with the server on its own. It's the same, but the client cannot discern the distinction. Client requests the resource and then receives it, without additional configuration required by the client.

Reverse proxies provide features like:

  • The web server is secured centrally.

  • Incoming traffic is directed based upon rules you set.

  • A new feature for caching is now available.

While central security is a benefit of both forward and reverse proxy servers. However, reverse proxy providers offer this feature to only the server layer, it is not available to the client layer. instead of the maintenance of firewalls at the server level that may contain multiple servers with various configurations, the bulk of firewall security is concentrated at the reverse proxy level. In addition, removing the responsibility of communicating with firewalls and connecting to client requests off web servers allows firewalls to focus on meeting the requirements of their customers.

In the event that there's multiple servers being hosted by a reverse proxy, it is also accountable for the way requests are routed to the server that is hosting them. Many web servers may be providing the exact same service, offering different types of resource or a combination of both. These servers may use their HTTP protocol to serve as a standard web server, however, they may also incorporate applications server protocols like FastCGI. It is also possible to set up reverse proxy servers to redirect users to specific servers based on the resource requested or to abide by certain guidelines for traffic load.

Reverse proxies can also benefit from their position in front of web servers, by providing caching capabilities. Large static assets can be set with caching rules in order to avoid hitting web servers with every request. There are options that allow users to serve static files without having to connect with the server on any manner. Additionally, reverse proxy is capable of compressing these assets.

The well-known Nginx web server functions as a powerful reverse proxy option. Although Apache is also a reverse proxy solution it is not the only one. Apache web server comes outfitted with reverse proxy functionality which is a feature that is available for Apache However, Nginx was originally designed to specifically focus on reverse proxy features.

The distinction in Forward Proxy and Reverse Proxy Use Cases

Since "forward" as well as "reverse" come with connotations of directionality and misleading analogies to "incoming" and "outgoing" traffic, these labels can be confusing as both types of proxies handle the processing of requests and replies. A better approach to differentiate between reverse and forward proxy is to study the requirements of the program you're creating.

Reverse proxy can be useful in the development of an application that connects web applications to the internet. They are your web servers whenever you connect to the internet.

Forward proxy are useful when used in front of customers for your personal use or in an office setting. They are your client's proxy when you interact with the internet.

Distinguishing by use case instead of focusing solely on common naming conventions can aid in avoiding confusion.


This article describes what a proxy is with two types: the reverse proxy and forward proxy. Practical examples of its use as well as a look at the advantageous features were used to differentiate forward proxies and reverse proxies.
