It is a proxy commonly known as a proxy server is software that acts as an intermediary between client and server over the internet. Without the use of proxy servers, users will send a request for resource directly to a server, and it would then serve the requested resource directly to the user. It isn't difficult to comprehend and implement. addition of proxies can bring advantages like improved performance, privacy, security, and many more. As a further layer of pass-through, proxies are a way to secure the internet, separating clients and servers.




The general set of server hardware along with the software used to install proxy is often referred too as proxy servers. This article will concentrate on proxies that are typically thought of as software, and in the context of web servers. The article will provide a description of the two types of proxies that are forward proxy and reverse proxy. forward proxy and reverse proxy. reverse proxy. Each has its own use scenario, which is often misunderstood due to the overlapping name convention.




This article will provide you with an overview of what proxies and their subtypes are, as well as how they work in common configurations. In this guide, you'll be able to understand what situations that using proxies can be advantageous, and choose the best option between reverse and forward proxy, in each circumstance.



Understanding Forward Proxies



In the same way forward proxy also called an open proxy serves as the representative of a customer who wishes to forward requests via the internet to an original server. In this case the client's attempts to send requests by the client are instead forwarded via the forward proxy. In this scenario the forward proxy acting in place that of the user will review the request. It is the first thing to check if the client is authorized to accept requests from this specific forward proxy. It will then either deny any request or forward it to its original server. The client is not able to have direct access to the internet; it can only connect to the internet that the forward proxy allows the client to access.




The most common reason for using forward proxies is to increase privacy or security on the internet. A forward proxy utilizes the internet in lieu of a client, and may use a different 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 many options and the ability to:




Beware of ad-tracker.


Circumvent surveillance.


Find restrictions based on your geographical place of residence.




Forward proxies are also used in systems that provide centralized security and access based on user permissions such as in the workplace. If all traffic on the internet flows via an open forward proxy, administrators could allow access only to a few users to the internet through the common firewall. Instead of putting firewalls for the client layer that could contain multiple devices with different settings and users and environments, a firewall may be set up at the forward proxy layer.




Be aware that forward proxy servers must be manually set up for use to be utilized, whereas reverse proxy servers are able to be not recognized by clients. Based on the fact that your IP address client is transferred to the server that originated it through the forward proxy privacy and anonymity can be granted or made more transparent.




There are a myriad of options to consider to find forward proxy options




Apache: A popular open-source web server, which offers forward proxy functionality.


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


Squid is a free forward proxy using the HTTP protocol. It doesn't provide the complete web server. Check out our article on the most efficient way to create 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 more suitable for situations such as peer-to-peer traffic. 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



Reverse proxy serves to act as an agent of web servers, which handles the incoming requests of customers on its behalf. The web server may consist of a single server or even multiple servers. In addition, it could serve for application servers, such as Gunicorn. In both cases, a request could originate from a user on the internet at large. Normally, this request is sent directly to the server which has the resources that the customer needs. In contrast, a reverse proxy functions as an intermediary in order to protect your web server from interactions with the internet's public.




From the perspective of a user, the experience of using reverse proxy is the same as connecting directly to your webserver. It's functionally identical and users can't tell the difference. Client requests a resource and receives it without any additional configuration or input from the end user.




Reverse proxies provide features such as:




Centralized security to web server.


The sending of traffic according to the rules you make.


New caching functionality has been added.




While central security is a benefit for both reverse and forward proxy systems, reverse proxy providers this service only to the server layer, and not to the layer that clients use. instead of maintaining firewalls on Web server layers that could include multiple servers that have different configurations, the majority of firewall security could be centered in the reverse proxy layer. In addition, getting rid of the burden of interfacing with a firewall as well as communicating with clients' requests away from web servers allows them to concentrate on addressing the needs of their customers.




In the event of multiple servers running in a reverse proxy,, the reverse proxy is also responsible to control which requests are placed on which server. There could be multiple web servers offering the identical service, with various kinds of resources, or a mix of both. They may use the HTTP protocol just like a standard web server, but they can also be equipped with applications server protocols, like FastCGI. A reverse proxy to send clients to specific servers based on the kind of resource they're searching for, or comply with specific rules regarding traffic volume.




Reverse proxies can also benefit from their placement on top of web servers, by providing the ability to cache information. The large static file can also be configured with caching policies to avoid the web server from being hit with every request. Certain solutions allow you to serve static content directly without touching the web server at all. In addition reverse proxy has the capability of compressing these files.




The popular Nginx web server can be described as a powerful reverse proxy solution. Although it is factual that Apache web server also comes with an reverse proxy however it's an additional attribute of Apache however Nginx was designed originally to focus on the reverse proxy function.



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



Since "forward" along with "reverse" are associated with directionality, and can lead to misleading comparisons with "incoming" as well as "outgoing" traffic. The labels are confusing because both kinds of proxies are able to handle requests and also respond. A better approach to distinguish between reverse proxy and forward proxy is to study the requirements of the application that you're developing.




Reverse proxy is a crucial element to consider when designing a system that can provide web-based applications on the internet. They act as your servers when you interact using the internet.




A forward proxy is beneficial when presented to individuals for personal use or in a corporate environment. They represent your clients whenever you use the internet.




Utilizing case-based distinction instead of focusing only on naming conventions that are similar can help avoid confusion.
