It is an proxy is sometimes referred to as a proxy server software program that acts to act as an intermediary the server and the client via the internet. Without a proxy, the client can send a request a resource directly to a server, and the server would then deliver the requested resource directly to the client. While this process is simple to comprehend and implement it is possible that the use of proxy servers can offer advantages such as enhanced performance, privacy, security, and so on. As a further layer of pass-through, proxies act as a security layer to the internet between users and servers.




In general, the combination of server hardware and proxy software is also often referred as a proxy server. This article we'll concentrate on proxies commonly thought to be software, specifically, in relation to servers on the internet. We will also discuss of the two principal kinds of proxies, which are two types: a forward proxy and a reverse proxy. Each has their own use case, but they can be confused because of a similar name convention.




This article will provide you with an understanding of what proxies and their subtypes are, as well as how they are useful for common setups. In this article you'll know what scenarios in which you can benefit from a proxy, and pick the best choice between forward and reverse proxy in each situation.



Understanding Forward Proxies



The forward proxy often called open proxy, also known as open proxy is an agent used by the user trying to make a request through the internet to an origin server. If this is the case, any requests from the client will instead be sent through an forward proxy. In this case, an agent acting on behalf of the forward proxy in in the place of the customer will review the request. The first step is to determine if the client is allowed to make requests via this particular forward proxy. It will then reject any request, or send it to the original server. The client does not have a access to internet in any way, it can only access what the forward proxy permits it to access.




The main reason people utilize forward proxy is to increase privacy or security on the internet. Forward proxy makes use of the internet as a client as such, it uses an alternative IP address to the IP address of your client.




Depending on how it's been set up in the past, forward proxy servers can provide a variety of features that allow you to:




Beware of ad-tracker.


Circumvent surveillance.


Find limitations based on your location.




Forward proxies may also be employed in systems that provide central security and access based on permissions like in workplaces. If all internet traffic is routed by an open forward proxy system, admins can restrict access to only certain clients to the internet via an common firewall. Instead of having firewalls on the client layer, which could include multiple machines with different configurations and users, a firewall may be added to an forward proxy layer.




Remember the forward proxy configurations have to be set up manually before they can be used to use them in reverse proxies, whereas forward proxies are able to not be observed by the user. The type of IP address the user's IP address, the server where it originated through the forward proxy, privacy and anonymity may be granted, or unnoticed.




There are a myriad of options to look into for forward-looking proxy services:




Apache The Apache is a well-known open-source web server that offers forward proxy features.


Nginx: Another well-known open-source server for hosting websites with forward proxy features.


Squid is an open-source forward proxy that utilizes the HTTP protocol. It's not the complete Web Server System. It is possible to refer to our tutorial on how you can create Squid proxy to connect privately in Ubuntu 20.04.


Dante forward proxy which runs on the SOCKS protocol, instead of HTTP which makes it more suited for scenarios such as peer-to-peer connections. It is also possible to research how to install an Dante proxy to allow private connections to Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy serves as an intermediary between a web server and takes responsibility for incoming requests from clients for the benefit of. This server could function as a single server, or as a series of servers. It could also be an application-server, such as Gunicorn. In either case, a request would originate from a user on the internet in general. In most cases, the request will be directed directly to a webserver that has all the information the user is seeks. Reverse proxy acts as an intermediary, shielding the webserver from direct contact with the open internet.




From a perspective of the user from a client's perspective reverse proxy isn't different from communicating with the server by itself. It's basically similar, but the user cannot tell the difference. Client asks for a resource gets it, without additional configuration from the client.




Reverse proxy providers provide features like:




The web server is protected centrally.


Incoming traffic is directed to you based on rules you set up.


The caching functionality has been added to the app.




While central security is an advantage of both reverse and forward proxy systems, reverse proxy providers provide offer this feature only to the web server layer, and not to the layer that clients use. instead of maintaining firewalls at Web server layers that may comprise multiple servers and various configurations, the bulk of firewall security can be concentrated at the reverse proxy layer. Furthermore, removing of the responsibility of interacting with firewalls and interfacing with requests from clients outside of web servers permits the firewall to concentrate on providing the necessary resources.




If there are multiple servers operating in reverse proxy and the reverse proxy takes care of the method by which requests are routed to which server. There are many web servers running on this server providing different kinds of resources or a mixture of both. These servers use the HTTP protocol just like a standard web server, but they can additionally include applications server protocols like FastCGI. It is possible to configure reverse proxy servers to send users to particular servers based on the type of resource they're searching for, or to observe certain guidelines on the volume of traffic.




Reverse proxies benefit from their position on top of web servers by virtue of caching. The large static files can be arranged with caching rules to avoid hitting web servers with each request. Some options allowing users to serve directly static files without having to connect directly to web servers at all. Additionally, the reverse proxy can manage compressing these assets.




The well-known Nginx web server also functions as an extremely popular reverse proxy service. While it's real that Apache web server is also equipped with reverse proxy features but it's a feature that is available for Apache but Nginx was designed originally for and is focused on reverse proxy features.



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



Because "forward" along with "reverse" come with connotations of directionality as well as misleading analogies to "incoming" and "outgoing" traffic These labels are prone to confusion because both types of proxies respond to requests and receive responses. Better yet, the best method to distinguish between reverse and forward proxy is to analyze the requirements of the application you're creating.




Reverse proxy is a useful tool when you're developing a solution to serve applications on the web via the internet. They represent your web servers every time you use the web.




Forward proxy can be useful for displaying clients to use for personal purposes, or in a work environment. The forward proxy displays the information of the client every time you connect to the internet.




Separating by use case instead of focussing on similar name conventions will ensure you aren't confused.



Conclusion



This article explains what a proxy is and compares the two main types, namely the reverse proxy and the forward proxy. Practical examples of use as well as a discussion of the most advantageous attributes were used to determine the difference between forward and reverse proxies.
