The term "proxy" refers to a proxy or proxy server. A proxy server is software that acts acting as a mediator between client and server via the internet. Without a proxy, the client could make a request for a source straight to the server, and it would serve the requested resource directly back to the user. This is not difficult to comprehend and implement, adding proxies provides advantages through improved security, performance, privacy, and much more. As a layer of pass-through, proxies serve as a security barrier on the internet between servers and clients.

The general combination of server hardware and installed proxy software is also commonly called proxy servers. This article will concentrate on proxy servers which are usually described as software, as well as ones that work in conjunction with web servers. This article will give details of the two main types of proxy servers, specifically the forward proxy and reverse proxy. reverse proxy. Each type has its own specific usage that can cause confusion due to the overlapping terminology.

This article will provide you with an understanding of nature of proxies and their subtypes and their value in the typical configurations. After reading this article, you'll be able recognize scenarios where an effective proxy is beneficial, and determine the most suitable choice between reverse proxy and forward proxy for any situation.

Understanding Forward Proxies

Also forward proxy, also referred to as open proxy open proxy is an agent for a user who is trying to transmit requests online to an server. In this situation every attempt to send requests made by the client is directed via an forward proxy. In this scenario, the forward proxy acting on behalf of the client, will look into the request. At the beginning it will decide if clients are authorized send requests through this specific forward proxy. Then, it will either deny requests or redirect them to the origin server. The client doesn't have a direct access to the internet and has access to only what the forward proxy permits it to connect to.

The most popular reason to use forward proxies is more privacy or protection on the internet. A forward proxy connects to the internet for an individual client and in this way it could make use of an IP address that is different from the original IP address used by the client.

Depending on the method by which it's set up, a forward proxy can provide a variety of features and the ability to:

  • Beware of ads-trackers.

  • Circumvent surveillance.

  • You can determine restrictions based upon your location.

Forward proxies are also used in systems to provide central security and permission-based access, for example in the workplace. When all internet traffic goes through a common forward proxy layer, administrators may allow only a handful of clients online access, which is filtered by an common firewall. Instead of establishing firewalls for clients, that can be utilized by multiple computers that have different configurations, users the firewall can be added to the forward proxy layer.

Keep in mind the fact that forward proxy servers must be manually set up before they are able to be used while reverse proxy servers could be not noticed by clients. Based on whether or not the IP address of the client is transmitted to the origin server by the forward proxy privacy and anonymity can be granted or hidden from view.

There are a myriad of choices to consider when it comes to forward proxy options.

  • Apache The Apache is a popular open-source web server, which provides forward proxy capabilities.

  • Nginx: Another popular open-source webserver that comes with forward proxy capability.

  • Squid is an open-source forward proxy that uses an HTTP protocol. It doesn't provide the full Web server platform. You can check out our guide on the best method of installing Squid proxy for private connections on Ubuntu 20.04.

  • Dante forward proxy, which uses on the SOCKS protocol rather than HTTP this makes it better to handle situations like peer-to-peer connections. You could also look into how to configure Dante proxy for private connections in Ubuntu 20.04

Understanding Reverse Proxies

A reverse proxy serves as an agent for a web server. It manages requests received by clients on its behalf. The web server could function as a single server, or as a series of servers. In addition, it could include an application servers, like Gunicorn. In any of these situations, a request could be made by a user of the internet. The request will typically be sent directly to the server on the internet that holds the data the client is asking for. A reverse proxy is a intermediary, separating the web server from direct interaction with the open internet.

From the point of view of the client, interacting using reverse proxy isn't any different than interacting directly with an internet server. It's exactly the same, but the client can't discern the distinction. The client requests an item and receives it, with no further configuration required for the customer.

Reverse proxy providers provide features like:

  • Centralized security for web servers.

  • The routing of traffic inbound is by rules you set up.

  • Additional functionality to cache data.

Although central security is an advantage of both reverse and forward proxies, reverse proxies provide this feature only to the layer that is on the webserver and not to the client layer. instead of maintaining firewalls on the server level which could comprise several servers that have various configurations, the bulk of firewall security could be focused at the reverse proxy layer. Additionally, removing the burden of dealing with firewalls and coordinating requests from clients off web servers allows the firewall to focus on providing resources.

If there are multiple servers running behind a reverse proxy the reverse proxy could be also responsible for directing what requests are directed to which servers. There could be multiple web servers operating within the same system, each serving different types of resources or a combination of both. The servers employ their HTTP protocol to serve as a normal web server. However, they can be equipped with other protocols for application servers such as FastCGI. You can set up a reverse proxy to route clients to specific servers based on the requested resource or to comply with certain guidelines regarding the traffic load.

Reverse proxies are also able to benefit from their positioning ahead of web servers by using caching functions. Large static assets can be configured using caching rules to avoid hitting web servers every request, with some solutions allowing you to serve static content without needing to connect to the servers in any manner. In addition, the reverse proxy can be capable of compressing these assets.

The well-known Nginx web server also functions as an effective reverse proxy solution. While Apache is a reverse proxy solution and this Apache website server additionally has reverse proxy capabilities, and is a different option to Apache and Nginx was originally designed to and specifically focuses on the reverse proxy features.

Differentiating Forward Proxy from Reverse Proxy Use Cases

Because "forward" or "reverse" are both associated with a sense of directionality, and false comparisons to "incoming" or "outgoing" traffic the labels could be confusing, because both types of proxies are able to handle both requests and responses. Better yet, the best method to distinguish between both forward and reverse proxy is to take into account the requirements of the application that you are developing.

A reverse proxy can be useful when you are creating a solution to serve web applications on the internet. They act as your web server in all interactions on the Internet.

Forward proxy can be useful when it is used before clients for personal use or in a business setting. They represent your clients for any interaction on the internet.

A case-based distinction instead of focusing solely on similar naming conventions will assist you in avoidance of confusion.


This article will explain what a "proxy" is and the two major types of proxies being the forward proxy and reverse proxy. Practical scenarios for its use as well as an examination of the beneficial characteristics were used to define the two types of proxies that are reverse and forward.
