It is an proxy commonly referred to as proxy server. It is a software that sits as an intermediary between the client and server on the web. Without the use of a proxy, a user could send a request for a resource directly to a server and it would serve direct to users. It's not hard to understand and implement the addition of proxies can bring advantages like improved performance, privacy, security, and more. As a further layer of pass-through, proxies act as a gatekeeper on the internet, separating clients and servers.




The general entire set of server hardware along with the software for proxy installation is often referred too as proxy servers. This article will concentrate on proxies traditionally understood as software, and in the context of web servers. This article will give a description of the two main types of proxies, which include a forward proxy and reverse proxy. reverse proxy. Each has its own usage case, often confused due to the similar namesake convention.




This article will give you an understanding of types of proxies, their subtypes, and how they work in the normal configurations. Through this article, you'll be able to understand how to identify the circumstances that using proxies can be advantageous, and choose the right option, based on forward and reverse proxy for each situation.



Understanding Forward Proxies



In other words forward proxy also called an open proxy acts as the representative of the customer who wishes to forward requests over online to the origin server. In this situation, all requests sent by the client are instead forwarded via the forward proxy. In this case, the forward proxy in the place of the client will review the request. It is the first thing to check if the client is authorized to accept requests from this specific forward proxy. The client will either decline any request or forward it to its original server. The client does not have an internet connection directly It can only access what forward proxy allows the client to access.




The most popular reason to utilize forward proxy servers is to gain greater privacy or security on the internet. A forward proxy utilizes the internet instead of a client, and in that process it could use an alternative IP address to the initial IP address of the client.




Depending on how it's been setup, and how it's set up, forward proxy may offer a range of features and also the capability to:




Beware of ad-tracker.


Circumvent surveillance.


Find restrictions based on your geographical area.




Forward proxies can also be used in systems that offer centralized security and access based on user permissions such as in the workplace. If all traffic on the internet flows through an open forward proxy layer, administrators can grant access only to specific users who are filtered through an ordinary firewall. Instead of having firewalls in place for the client layer which could include several devices that have different settings, users, and settings, a firewall may be added to this forward proxy layer.




Note that forward proxy server must be manually configured for use to be used, while reverse proxy servers are able to be ignored by clients. Based on whether or not an IP address from the user is transferred to the origin server through the forward proxy privacy and anonymity may be granted or made clear.




There are many options to consider options for forward proxy options




Apache: A popular open-source webserver that provides forward proxy functions.


Nginx: Another well-known open-source webserver with forward proxy functionality.


Squid: A no-cost forward proxy based on the HTTP protocol. It doesn't provide the complete web server. Check out our article on the most efficient method of creating Squid proxy to allow private connections within Ubuntu 20.04.


Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP which makes it more to handle situations like peer-to-peer communication. It's also a good idea to look into how to configure a Dante proxy to connect privately using Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy acts as an agent for a web server, handling any requests that come in from customers on behalf of the server. The web server may consist of a single server or multiple servers. It could also be used for application servers, such as Gunicorn. In any case, the request can come from a customer via the web in general. In most cases, the request is sent directly to the website server with the resources the client needs. In contrast, a reverse proxy functions as an intermediary to isolate your website server from any interactions with the internet's public.




From a client's perspective the experience of using reverse proxy isn't different than communicating directly with your webserver. It's basically identical and users can't tell the difference. Client requests resources and is then able to receive it without any additional configuration or input from the end user.




Reverse proxies provide features such as:




Security centralized for web servers.


Directing traffic in accordance with rules you create.


New functionality added for caching.




While centralized security can be a benefit of both reverse and forward proxy platforms, reverse proxy provides this service to only the server layer and not to the client layer. Instead of focusing on maintaining firewalls for servers on the internet, which could contain multiple servers that have different configurations, the bulk of firewall security can be concentrated to the reverse proxy layer. Furthermore, removing the hassle of connecting to a firewall as well as dealing with requests from clients far from web servers permits the firewall to concentrate on meeting the requirements of their customers.




If there are multiple servers running behind a reverse proxy, the reverse proxy is also accountable for deciding which requests go on which server. There may be several web servers providing the exact identical service, with different types of resources or a combination of both. They can use the HTTP protocol like a traditional web server, however they could also be outfitted with applications server protocols, like FastCGI. A reverse proxy is used to connect clients to specific servers based on the kind of resource they are looking for, or to comply with specific rules regarding traffic volume.




Reverse proxies may benefit from their position on top of web servers through the ability to cache data. The large static file can also be set up using caching rules to prevent the web server from being hit with every request. Certain solutions allow you to deliver static content directly without ever touching the web server in any way. Additionally reverse proxy has the capability of the compression of these assets.




The popular Nginx web server is a powerful reverse proxy option. While it's real that Apache web server comes with a reverse proxy feature, however it's a distinct function of Apache but Nginx was initially designed for and focuses on reverse proxy functions.



Distinguishing Forward Proxy From Proxy Use Differentiating Forward Proxy and Reverse Proxy Use



Since "forward" as well as "reverse" have connotations of directionality and misleading comparisons with "incoming" and "outgoing" traffic. These labels are confusing because both types of proxy can handle requests and also respond. A better approach to differentiate between reverse or forward proxies is to look at the requirements of the application that you are developing.




Reverse proxy is a crucial feature when designing a solution that can provide web-based applications on the internet. They serve as your servers when you are connected to the internet.




A forward proxy is beneficial when presented to users for personal usage, or even in a commercial setting. They represent your clients when you interact with the internet.




The use case-based differentiation instead of focusing solely on similar naming conventions can help avoid confusion.



Conclusion



The article clarified what a proxy was and the two kinds of them being the both reverse and forward proxy. Application scenarios that can be used in practical situations as well as an analysis of features that are useful were utilized to differentiate between forward and reverse proxies.
