It is an proxy is also referred to as proxy server, which is a software that acts acting as an intermediary between a client and server on internet. Without the use of a proxy, users could send a request for a resource directly to a server, and it would serve direct to users who requested the resource. While this approach is straightforward to grasp and implement, using proxies provides benefits in terms of more performance, privacy, security, and much more. As an additional layer of being able to pass through, a proxy acts as a gatekeeper for the internet, separating clients and servers.

The general consensus is it is the case that the mix of servers hardware with installed proxy software is often referred too as proxy servers. For this post, we will focus on proxies typically described as software, as and those utilized together to web server. This article will present a detailed breakdown of two types of proxy such as a forward proxy and a reverse proxy. Each comes with its own specific use case that is frequently confused due to the similar namesake convention.

This article will provide an understanding of the different types of proxy and their subtypes, and the ways they can be useful for the most common setups. By reading this article you’ll be able identify the circumstances where a proxy can be advantageous, and choose the best reverse or forward proxy in any given situation.

Understanding Forward Proxies

The forward proxy, also known by the name of an open proxy is a representative of a user who attempts to transmit an internet request to an origin server. In this scenario, it’s the scenario that all requests made by the client will be directed via through the forward proxy. In this scenario the forward proxy, in lieu of the client will review the request. In the beginning, it decides if the client is permitted to forward requests through this specific forward proxy. Then, it decides to deny this request as well as forward it to the origin server. It’s not able directly connect via the Internet. It is only able to access the information the forward proxy allows it access to.

The most common use for forward proxies is for greater privacy or security on the internet. Forward proxy utilizes the internet as an individual client. In this process, it can utilize a different IP address in opposition to the IP address of the client.

Depending on how they were set up in the past forward proxy servers may give you a variety of options, allowing you to:

Forward proxies are also employed in systems that offer central security and permit-based access, such as in the workplace. If all internet traffic is routed through an open forward proxy layer, the administrator is able to permit only a few clients access to the internet, which is filtered by a common firewall. Instead of maintaining firewalls for the client layer which can include multiple machines that are different in terms of user and environment the firewall could be installed at the layer that redirects traffic from proxy servers.

Keep in mind that forward proxy servers have to be set up manually prior to be used, while reverse proxies are often not recognized by clients. Based on the fact that clients’ IP addresses are sent to the origin server through the forward proxy Privacy and anonymity may get granted, or even made more transparent.

There are many options to be considered when it comes to forward proxy options:

Understanding Reverse Proxies

Reverse proxy is a representative of a web server that manages requests from customers on its behalf. The web server could represent a single or multiple servers. Furthermore, it could serve as an app server, like Gunicorn. Any of the above scenarios, it is possible to receive a request via a user on the internet in general. The majority of the time the request will be delivered directly to the web server along with the data the user wants. The reverse proxy is a intermediary to isolate your web server from interaction with the internet.

From a user’s point of view from the perspective of a customer using a reverse proxy is no different from communicating with the webserver in direct communication. It’s the same thing, and the client is unable to discern the difference. The client requests a resource and then receives it, without any extra configuration required by the end user.

Reverse proxy proxies are able to provide some features, including:

While central security is a benefit of both reverse and forward proxy service, reverse proxy provides this benefit to only the server layer and not to the client layer. Instead of the maintenance of firewalls in the layer of web servers which can contain several servers that have different configurations, the majority of firewall security is centered in the reverse proxy layer. In addition, the removal of the requirement of interfacing with firewalls and responding to requests from clients far from web servers allows firewalls to concentrate on serving the needs of their clients.

If there are multiple servers that are in a reverse proxy, the reverse proxy will also take care of how requests are routed to which server. Multiple web servers may be running on the same server, providing different types of resources, or a mix of the two. They can be using the HTTP protocol to function as a standard web server. They can include applications server protocols such as FastCGI. It is possible to set up a reverse proxy to direct clients to specific servers according to the type of resource they’re looking for, or to comply with certain rules regarding traffic load.

Reverse proxies can also benefit from their positioning prior to web servers, by providing the capability of caching. Large static assets can be configured using caching rules to prevent hitting web servers on each request, with certain solutions providing the option to directly serve static resources without having to connect to the internet server at all. Furthermore reverse proxy can handle the compression of these assets.

The popular Nginx web server also functions as an acknowledged reverse proxy provider. While you can use Nginx, the Apache web server, it’s also equipped with reverse proxy feature, it’s a separate option that’s available to Apache however Nginx was originally designed and focused on reverse proxy functions.

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

Due to the fact that “forward” as well as “reverse” are associated with the notion of directionality, and false distinctions between “incoming” as well as “outgoing” traffic These labels are confusing because both types of proxies can respond to requests as well as responses. A better approach to distinguish between reverse and forward proxies is to examine the specifications of the application you’re developing.

A reverse proxy can be helpful in the development of a solution to provide web-based applications on the internet. They act as your servers whenever you connect to the internet.

Forward proxy are beneficial when they are used before a client for personal use, or in the workplace. They are a representation of your traffic when you are on the internet.

A distinction that is based on the use case rather than focusing only upon similar conventions for naming will aid in avoiding confusion.


This article explains the definition of a proxy that includes two main kinds: the forward proxy and the reverse proxy. Practical application scenarios and a look at beneficial features was used to differentiate forward proxies and reverse proxies.
