It’s a proxy or proxy server. It is a software which acts as an intermediary between client and server on the internet. With no proxy in place, a customer can send a request to an entity directly through a server and the server will provide an item directly to the user. While this approach is straightforward to comprehend and implement using proxy services, it may provide advantages in terms of better performance as well as privacy, security and more. A pass-through layer in addition to proxy is an extra security layer on the internet between servers and clients.

It is generally accepted that the collection of server hardware along with installed proxy software is also frequently called proxy servers. This article will focus on proxy servers which are usually described as software and also in the context of web servers. This article will provide an extensive description of two primary types: a forward proxy and a reverse proxy. reverse proxy. Each type has its own usage instance, but they often get confused because of the identical name-based convention.

This article will provide information about what proxies are and the subtypes of them, and how they work in the most common configurations. In this article, you’ll be able to identify the circumstances in which you may benefit from a proxy, and decide on the most appropriate solution between reverse proxy and forward proxy for any situation.

Understanding Forward Proxies

The forward proxy also known as an open proxy is an intermediary for a customer who would like to transmit a request over the internet to an original server. In this scenario it is the case that all requests made by the user would prefer to be handled by this forward proxy. A forward proxy acting in place of the client will scrutinize the request. The first step is to decide if the client is permitted to make requests through this particular forward proxy. Then, it will either deny the request or forward it to the original server. The client does not directly connect to the Internet. It only has access to the internet that forward proxy permits it to connect to.

The most frequent uses for forward proxies is to gain increased privacy or anonymity on the internet. Forward proxy utilizes the internet as the client, and in this manner, it may utilize an alternate IP address that is different to the client’s initial IP address.

Based on the way it has been set up depending on how it is configured forward proxy could give you a variety of options. It will allow you to:

  • Avoid tracking ads.

  • Circumvent surveillance.

  • You can identify limitations based on your geographic place of residence.

Forward proxies also are used in systems that offer central security and access via permissions, like in workplaces. If all internet traffic flows through a standard forward proxy, an administrator could permit only a few clients online access which is filtered by a common firewall. Instead of putting firewalls for the client layer that can include multiple machines that have different configurations and clients, the firewall can be placed within the layer that forwards proxy-related traffic.

Be aware that forward proxy servers need to be manually setup to use them, while reverse proxy servers could go unnoticed from the customer. Depending on the kind of IP address of the customer, if it is relayed back to the origin server through the forward proxy, privacy and security can be granted, or not be noticed.

There are many possibilities to consider when it comes to forward proxy choices:

  • Apache An open-source, well-known web server that provides forward proxy features.

  • Nginx is another well-known open-source web server that has the ability to forward-proxy.

  • Squid is an open source forward proxy which uses the HTTP protocol. This doesn’t offer an entire web server service. It is possible to refer to our step-bystep guide for setting up Squid proxy for private connections in Ubuntu 20.04.

  • Dante Forward Proxy that uses the SOCKS protocol instead HTTP which is more suitable for peer-to-peer traffic. You could also find out how to install a Dante proxy for private connections on Ubuntu 20.04

Understanding Reverse Proxies

Reverse proxy serves as a representative of a web server that handles any requests that come in from clients on behalf of. The web server could comprise a singular server, or multiple servers. It could also function as an application server, such as Gunicorn. In both cases, the request is received from a client through the web at large. Most of the time the request will go directly to the server with the information the client is in need of. Reverse proxy, however, functions as an intermediary and separates it from direct interaction with the internet’s open.

From the viewpoint of the client, interacting with reverse proxy is not any different from interacting with the web server directly. It’s exactly the same, and the client is unable to tell the distinction. The client makes a request for an item, it then gets it, with no extra configuration needed from the client.

Reverse proxy providers provide features like:

  • The web server is protected centrally.

  • Directing traffic according to rules that you can determine.

  • Additional functions to cache data.

While central security is an advantage of both forward and reverse proxy services, reverse proxies give this benefit to Web layer servers, but not to the layer of clients. instead of having firewalls at the web server layer which may include multiple servers with different configurations, the majority of firewall security lies at the reverse proxy layer. Furthermore eliminating the responsibility of communicating with firewalls and coordinating requests from clients who aren’t connected to web servers lets them concentrate on delivering the needs of their clients.

In the case of multiple servers running in a reverse proxy the reverse proxy is also responsible for controlling which requests go through which server. There could be multiple web servers hosting the same resources, providing various kinds of resources or a mixture of both. They can utilize the HTTP protocol in the same way as a traditional web server but include other protocols for application servers such as FastCGI. It is possible to configure reverse proxy services that redirects clients to particular servers based on the requested resource or to follow specific guidelines for traffic load.

Reverse proxies can also benefit by their position in front of web servers, providing caching functions. Massive static images can be set up by caching rules, avoiding having to contact web servers for every request. There are even solutions offering an option to serve static files directly without touching the web server for any reason. In addition, the reverse proxy can handle the compression of these files.

The well-known Nginx web server is also used as a very popular reverse proxy service. Although Apache is also a reverse proxy solution, the Apache web server is also equipped complete with reverse proxy, which is an additional feature for Apache However, Nginx was initially developed for and is focused exclusively on reverse proxy feature.

Differentiating Forward Proxy and reverse Proxy Use Examples

Since “forward” or “reverse” are both associated with an impression of directionality and are misinterpreted as comparing “incoming” in addition to “outgoing” traffic These labels could be confusing since both kinds of proxies respond to requests and other responses. The best way to differentiate between reverse and forward proxy services is to study the requirements of the app you’re creating.

Reverse proxy is a useful tool to develop a solution to offer web-based services via the internet. They serve as your web servers when you connect to the internet.

Forward proxy software is useful to display clients for personal use, and even in a professional setting. They are your client’s proxy for any interaction online.

The practice of separating by use case rather than focussing on the common naming conventions can make it simpler to avoid confusion.

Conclusion

This article describes what a proxy is along with two kinds, namely the forward proxy and the reverse proxy. Practical applications as well as a brief overview of the beneficial features were used to distinguish forward proxies from reverse. If you’re interested in exploring the possibilities of proxies then you should read our guide on how to configure Nginx as an reverse proxy and internet server within Apache running an Ubuntu 20.04 server.
