A proxy is also known as a proxy server software which acts as a mediator between a client and server on the internet. Without the need for proxy servers, users could send a request to resources directly to a server and servers would provide the requested resource directly to the user. Although this may be a straightforward process to grasp and use the addition of proxies can provide benefits like improved performance and privacy, security and many more. As a pass-through layer, proxies act as a gatekeeper of the internet between clients and servers.

In general, the integrated combination of server hardware and installed proxy software is commonly referred as proxy servers. This article will focus on proxy servers which are generally referred to as software, and as when referring to web servers. This article will give an explanation of the two primary kinds of proxy servers, which include a forward proxy and reverse proxy. reverse proxy. Each type has a distinct use case, often confused due to the identical namesake convention.

This article will provide you with an understanding of types of proxy services, what their subtypes are, as well as how they are helpful for setups that are common. If you read this article, you'll to recognize situations where it is beneficial to use the proxy service and determine the best option between forward proxy and reverse proxy in any circumstance.

Understanding Forward Proxies

The forward proxy also referred to as or an open proxy acts as the agent of the client, trying to send an online request to the server that made it. In this scenario, all attempts to send requests from the user are instead sent direct via the forward proxy. In this situation, the forward proxy on behalf of the client will examine the request. It first will determine if the client can make requests using this specific forward proxy. Then, it can either deny requests or redirect it to the server it originated from. The client isn't able to have an internet connection directly. It has access to only what forward proxy allows for it to link to.

The primary reason people use forward proxies is to gain greater privacy or security on the internet. A forward proxy utilizes the internet instead of an individual client and, in doing so it can utilize an alternate IP address to the original IP address used by the client.

Depending on how it's been configured, a forward proxy can provide a variety of functions and allow you to:

  • Beware of ads that track you.

  • Circumvent surveillance.

  • Establish restrictions based upon the location.

Forward proxies are also utilized in systems that provide centralized security and access based on permissions, such as in a workplace. If all traffic on the internet flows through an open forward proxy layer the administrator can grant only a few clients connection to internet via a common firewall. Instead of establishing firewalls on the client layer, which can involve many machines that have different settings and users you can put the firewall configured on the proxy layer that is front.

Be aware that forward proxy servers need to be set up manually for their use, whereas reverse proxies can be ignored by clients. Based on the type of IP address of the client is sent to the source server via forward proxy privacy and security may be granted or kept in the dark.

There are several options to consider for forward proxy options:

  • Apache is an well-known open-source web server, that offers forward proxy capabilities.

  • Nginx: Another popular open-source webserver that includes forward proxy capabilities.

  • Squid is an open source forward proxy which utilizes the HTTP protocol. The option does not include the entire website server program. You can read our tutorial on how you can use Squid proxy to allow private connections in Ubuntu 20.04.

  • Dante is a forward proxy that runs using the SOCKS protocol instead of HTTP to make it more suited for cases such as peer-to-peer communication. It is also possible to learn how to create an Dante proxy to permit private connections on Ubuntu 20.04

Understanding Reverse Proxies

A reverse proxy functions as an agent for a web server that handles any requests that come in from clients on behalf. The web server can comprise one server or several servers. Additionally, it can be used as an app server, such as Gunicorn. In all of these scenarios, a request would come from a user via the internet in general. The majority of the time, this request is sent directly to the website server hosting the information that the user is seeking. Instead, a reverse proxy acts as an intermediary to shield Web server from direct interaction with the internet's public.

From a consumer's point view from a client's perspective using a reverse proxy is no the same as working with a Web server in direct contact. It's basically the same, but the client can't discern the difference. Client requests the resource, and then it receives it, with no extra configuration required from the user.

Reverse proxies provide features like:

  • A central layer of security that protects the server.

  • Controlling traffic coming inbound on rules you can define.

  • New caching functionality has been added.

Although central security is an advantage of both forward and reverse proxy servers, reverse proxies offer this feature only to the layer of the webserver and not to the client layer. instead of maintaining firewalls at the server level that may include multiple servers that have different configurations, the bulk of security for firewalls is centered upon the reverse proxy. Also, the removal of the responsibility to interact with firewalls and interfacing with client requests via web servers allows firewalls to concentrate on providing the resources.

In the case of multiple servers connected to a reverse proxy, the reverse proxy also is responsible for directing which requests go at which server. There may be several web servers providing the same content, providing various kinds of services, or a combination of both. They could use the HTTP protocol in the same way as the traditional web server. However, they can also be equipped with applications server protocols like FastCGI. You can configure reverse proxy software to redirect visitors to a particular server based on the service being requested, or to adhere to specific rules regarding traffic load.

Reverse proxies can also benefit from their positioning prior to web servers through the ability to cache data. Large static assets can be configured with caching rules to avoid needing to connect with web servers every time you request. There are some solutions even allowing users to serve static files directly without having to connect to the web server for even one time. In addition the reverse proxy can deal with the compression for these files.

The well-known Nginx web server can also function as a powerful reverse proxy option. However, Apache is also a reverse proxy option but it is a reverse proxy solution. Apache web server is also fitted with an reverse proxy function as an additional feature for Apache unlike Nginx was initially developed for and is focused on reverse proxy capabilities.

Distinguishing Forward Proxy from Reverse Proxy Use-cases

Because "forward" and "reverse" have connotations of directionality, as well as inaccurate comparisons with "incoming" and "outgoing" traffic The labels could be confusing because both types of proxies deal with both requests as well as responses. The most effective way to differentiate between reverse and forward proxy is to look at the requirements of the app you're working on.

Reverse proxy can be a valuable tool when you are developing a solution to serve web-based applications via the internet. They represent your web servers every time you use the web.

A forward proxy is helpful when placed in front of clients for personal use and in professional environment. They are a representation of the client's online traffic in any online interaction.

The practice of separating by use case instead of using the same names can help in avoiding confusion.


This article explains the meaning of a proxy with two types being the forward proxy and the reverse proxy. Practical application scenarios and an examination of the beneficial attributes were used to distinguish forward proxies and reverse proxies.
