It is an proxy often known as proxy server software that acts as an intermediary between the client and server over the internet. Without proxy, a user would make a request a resource directly to a server and it would deliver direct to users. This is not difficult to comprehend and apply the proxy feature can provide advantages like improved performance as well as privacy, security and so on. As an additional layer of security, proxies are a way to secure the internet between clients and servers.

It is generally accepted that the set of server hardware along with the software for proxy installation is commonly referred to as proxy servers. This article will focus on proxies that are typically thought of as software, and also in relation to web servers. The article will offer a description of the two main kinds of proxies. They comprise forward and reverse. forward proxy and reverse proxy. reverse proxy. Each has its own usage scenario, which is often misunderstood due to the similar namesake convention.




This article will give you an overview of nature of proxies and subtypes, and how they function in typical setups. In this guide, you'll be able to understand how to recognize the situations that using proxy servers is advantageous, and choose the right option, based on reverse and forward proxy, depending on the situation.



Understanding Forward Proxies



In other words, a forward proxy sometimes called an open proxy acts as the representative of a customer who wants to send requests via on the web to an original server. In this situation the client's requests sent by the client will instead be forwarded via the forward proxy. In this situation the forward proxy acting in place in the place of the customer will examine the request. The first step is to determine whether the client is authorized to receive requests from this particular forward proxy. The client will either decline the request or forward it to its origin server. The client doesn't have a direct connection to the internet; it can only connect to what forward proxy allows it to connect to.




The most popular reason to utilize forward proxy servers is to increase privacy or security online. A forward proxy utilizes the internet in lieu of a client and in that process it could use an alternative IP address that is different from the client's initial IP address.




Based on the way it's set up depending on how it's set up forward proxy could provide a range of options and the capability to:




Avoid ad tracking.


Circumvent surveillance.


Find restrictions based on your geographical area.




Forward proxies are also used in systems that offer central security and access based on permissions like in the workplace. If all internet traffic flows through an open forward proxy layer administrators could allow access only to a few users to the internet by a common firewall. Instead of having firewalls in place for the client layer which may contain several devices that have different settings and users and settings, a firewall may be added to this forward proxy layer.




Note that forward proxy server need to be manually set up to use in order to be utilized, whereas reverse proxies are able to be ignored by clients. Based on the fact that your IP address user is transferred to the server that originated it through the forward proxy, privacy and anonymity can get granted, or even made clear.




There are many possibilities to consider to find forward proxy options




Apache: A popular open-source web server that offers forward proxy capabilities.


Nginx: Another well-known open source webserver that has forward proxy capabilities.


Squid: A free forward proxy based on the HTTP protocol. It doesn't provide the complete web server. We recommend you read our guide on the best method of creating Squid proxy to allow private connections in Ubuntu 20.04.


Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP, which makes it better to handle situations like peer-to-peer traffic. It is also possible to look into how to configure a Dante proxy to connect privately on Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy acts to act as an agent of a web server, handling any requests that come in from customers on its behalf. The web server could be comprised of one server or multiple servers. It could also serve in the role of an application server, such as Gunicorn. In both cases, a request could be made by a client via the internet at large. The majority of the time, this request will be directly to the web server with the resources the client is in need of. Instead, a reverse proxy works as an intermediary in order to protect your website server from any interactions with the internet's public.




From the perspective of a user, the experience of using reverse proxy is not different from communicating directly with your webserver. It is functionally identical, and the user cannot tell the distinction. Client requests resources and then receives it, without any additional configuration required from the user.




Reverse proxies provide features such as:




Security centralized for web servers.


Directing traffic according to the rules you create.


New functionality added for caching.




While centralized security can be a benefit of both forward and reverse proxy systems, reverse proxy provides this service to only the server layer and not to the client layer. In lieu of maintaining firewalls on Web server layers which could contain multiple servers that have different configurations, the bulk of firewall security could be focused in the reverse proxy layer. Furthermore, getting rid of the responsibility of interacting with firewalls as well as dealing with requests from clients far from web servers permits them to focus solely on meeting the requirements of their customers.




In the case of multiple servers that are connected to a reverse proxy the reverse proxy is also responsible for controlling which requests go to which server. There could be multiple web servers that provide the same service, serving different types of resources or a combination of both. They may use the HTTP protocol as a conventional web server, but they can also be equipped with application server protocols such as FastCGI. A reverse proxy can be used to direct clients to specific servers based on the kind of resource they're searching for, or adhere to specific rules for traffic load.




Reverse proxies may benefit from their placement on top of web servers by offering the ability to cache information. Large static files can be configured using caching policies to stop the web server from being hit with every request. Certain solutions allow you to serve static content directly without ever touching the web server in any way. In addition reverse proxy has the capability of the compression of these assets.




The popular Nginx web server can be described as an effective reverse proxy option. Although it is factual that Apache web server also comes with a reverse proxy, however, it's a separate attribute of Apache but Nginx was initially designed to and is focused on reverse proxy functions.



The distinction between Forward and Reverse Proxy Use. Differentiating Forward and Reverse Proxy Use



Because "forward" along with "reverse" can be interpreted as directionality, they can be misleading when comparing "incoming" or "outgoing" traffic. The labels are confusing because both kinds of proxies are able to handle requests and also respond. The best way to differentiate between reverse and forward proxy is to study the requirements of the app that you're developing.




Reverse proxy is a crucial element to consider when designing a system that allows web-based applications over the internet. They serve as your servers when you interact using the internet.




A forward proxy is useful when it is placed in front of individuals for personal use or even in a business environment. They represent your clients when you interact with the internet.




The use case-based distinction instead of focusing only on similar names will help you avoid confusion.



Conclusion



The article clarified what a proxy was and the two kinds of them: both reverse and forward proxy. Application scenarios that can be used in practical situations as well as an analysis of the most useful features were used to distinguish between forward and reverse proxy. If you're looking to know more about the advantages of proxies, then you should read our guide on how to set up Nginx as an internet server and reverse proxy for Apache on an Ubuntu 20.04 server.
