It is an proxy is also referred to proxy server, which is a software that sits as a mediator between a client and server over the internet. Without the use of a proxy, users will send a request for a resource directly to the server and it would deliver direct to users who requested the resource. Although this method is easy to grasp and implement, using proxies provides advantages in the form of greater performance as well as privacy, security and more. As an additional layer for moving through, a proxy acts as a guardian to the internet between users and servers.

The majority of people agree it is the case that the mix of servers hardware with installed proxy software is frequently referred too as proxy servers. This article we’ll concentrate on proxies that are typically described as software, as well as those that are utilized to work in conjunction using web servers. This article will give the full description of two kinds of proxies: that is one that is a forward proxy and reverse proxy. reverse proxy. Each type comes with its own specific use case, often confused because of the similar namesake convention.

This article will give you an understanding of the different types of proxy and subtypes they have, and what ways they can be useful for the most common setups. By reading this article you’ll be able identify the circumstances in which a proxy is useful, and then decide the best forward proxy or reverse proxy for a particular scenario.

Understanding Forward Proxies

The forward proxy also referred to in the form of an open proxy is a representative of a client who is trying to route an internet request to an source server. In this case, it’s the case that all requests from the client are sent to this forward proxy. In this case the forward proxy, instead of the client will review the request. It will first will determine if the client is allowed to send requests via this particular forward proxy. It then decides whether to deny this request and transfer it over to the origin server. It’s not able direct connection to the internet. It only has access to what forward proxy permits it to access.

A typical use of forward proxies is for more privacy or security online. A forward proxy uses the internet as an individual client, and during this manner, it may use another 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 offer a wide range of choices, allowing you to:

Forward proxies are also employed in systems to provide central security and permission based access, such as in a workplace. In the event that all internet traffic is routed via an open forward proxy,, an administrator is able to grant only a handful of users connection to internet, that is blocked by a standard firewall. Instead of establishing firewalls at the level of client that can include multiple machines that are different in terms of user and environment the firewall can be placed at the layer that forwards proxy traffic.

Remember that forward proxies have to be manually setup to use, whereas reverse proxy are often not recognized by clients. Depending on whether an IP address is passed on to the origin server via the forward proxy Privacy and anonymity can get granted, or even made more transparent.

There are a myriad of possibilities to consider for forward proxies:

Understanding Reverse Proxies

Reverse proxy is a representation of a web server that handles incoming requests from customers on behalf of. Web servers can represent one or more servers. Furthermore, it could be an application server like Gunicorn. Any of the above situations a request could come in from a client through the internet at large. In most cases the request is directed directly to the server along with the data the user wants. Reverse proxy, however, serves as an intermediary and isolates your web server from interaction with the open internet.

From the perspective of a customer from a client’s perspective reverse proxy is no different from communicating with your webserver directly. It’s basically the same, and the client can’t discern the difference. Client requests a resource, which is followed by receiving it, with no additional configuration needed for the user.

Reverse proxy proxies may offer some features, including:

While central security is a benefit of both forward and reverse proxy service, reverse proxy providers provide this benefit only to the server layer, not to the client layer. Instead of the need to maintain firewalls at the web server layer which may include multiple servers with different configurations, the majority of firewall security is concentrated on the reverse proxy layer. In addition, the removal of the requirement of working with firewalls as well as communicating with requests from clients who aren’t connected to web servers allows the firewall to focus on the requirements of their clients.

If there are multiple servers that are connected to a reverse proxy the reverse proxy is also in charge of how requests are routed on the server. There could be multiple web servers running on the same server, serving various kinds of resources or a combination of both. These servers can use the HTTP protocol as a conventional web server. They may also include applications server protocols like FastCGI. You can set up reverse proxy servers to send clients to specific servers according to the type of resource they are seeking, or to follow certain rules to manage traffic load.

Reverse proxies can also benefit from their placement before web servers by delivering the capacity of caching. Large static assets are able to be configured using caching guidelines to avoid hitting web servers on each request, with certain services providing the option to directly serve static resources without having to connect with the server even once. Furthermore reverse proxy can be able to handle compression of these assets.

The popular Nginx web server also functions as known as a reverse proxy service. While you can use Nginx, the Apache web server, it is equipped with a reverse proxy features however it’s an additional feature that is available for Apache however Nginx was initially designed for and focused on reverse proxy functionality.

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

Because “forward” or “reverse” have connotations of directionality, and false connections to “incoming” in addition to “outgoing” traffic These terms can be confusing since both kinds of proxy can handle requests as well as responses. An alternative method to differentiate between reverse and forward proxy services is to study the requirements of the app you’re developing.

A reverse proxy can be beneficial in the development of a solution to provide web-based applications over 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 your personal use, or in a workplace setting. They represent your client traffic whenever you use the internet.

A distinction based on use cases instead of focusing exclusively upon similar conventions for naming will aid in avoiding confusion.


This article provides the definition of a proxy that includes two major types of proxy: the forward one and reverse proxy. Practical application scenarios and a look at beneficial features was used to distinguish between forward proxy and reverse proxy.
