A proxy is also known as an application called a proxy that acts as an intermediary between the server and user on the internet. In the absence of proxies, a customer could send a request to the service directly from a server and the server would serve the requested resource directly back at the requester's. While this approach is straightforward to grasp and implement, the addition of proxies can bring benefits such as improved performance and security, privacy, and more. As an additional layer of pass-through, the proxy serves as a gatekeeper of the internet between servers and clients.



Generally speaking, the combined combination of server hardware with proxy software is usually referred too as proxy servers. This article will concentrate on proxies that are traditionally classified as software in the context of web servers. This article will provide the full description of two types: the forward proxy and reverse proxy. reverse proxy. Each type of proxy has its own scenario, which is often not understood due to the similar terminology.



This article will provide details on what proxy services and their subtypes are, and how they work with a range of configurations. By reading this article, you will be able identify instances where the use of proxies is advantageous and pick the most appropriate solution between reverse and forward proxy in any given scenario.



Understanding Forward Proxies



The forward proxy, sometimes referred to as an open proxy serves as a representative for a user who wishes to make an internet-based request to an the server that originated it. In this scenario the entire effort to send requests by the user will be sent through the forward proxy. A forward proxy acting in place of the client will take a look at the request. It will then determine whether this client is authorized to send requests using this specific forward proxy. It will then decide whether to deny any request or send it to the source server. The client does not have direct access to the internet. It can access only what the forward proxy allows it access to.



A popular use for forward proxy is to provide greater privacy or security when using the internet. Forward proxy allows access to the internet in place of a client and in this way, it could use a different IP address than the original IP address of the client.



Depending on how it's been configured and how it is configured, forward proxy may grant you various features depending on how it is configured, which allows you to:




  • Don't fall victim of ad trackers.


  • Circumvent surveillance.


  • Be aware of restrictions based on the place of residence.



Forward proxies are also used to secure systems that are centralised as well as access that is permission-based, like at a workplace. When all internet traffic passes through an open forward proxy an administrator can grant only a small number of clients connection to internet by the standard firewall. Instead of creating security firewalls at the layer of clients which can comprise a variety of machines that have different environments and types of users A firewall can be installed at the forward proxy layer.



It is important to remember that forward proxies must be manually configured to use and reverse proxies may be hidden from the user. Depending on the type the IP address that the user who is transferred to the server that is originally via forward proxy Privacy and anonymity could be granted or not.



There are a variety of alternatives to look into for forward proxies.




  • Apache An open source well-known web server, which offers forward proxy functions.


  • Nginx: Another popular open-source web server that has forward proxy capabilities.


  • Squid: A free forward proxy that uses an HTTP protocol. It doesn't provide the complete web server. Read our article on the best way to build a Squid proxy for private connections in Ubuntu 20.04.


  • Dante is an forward proxy that utilizes the SOCKS protocol instead of HTTP and HTTP making it more suitable for applications such as peer-to-peer traffic. It is also possible to learn how to configure Dante proxy to allow private connections on Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy is an intermediary for a web server, which handles the incoming requests of clients on its behalf. The web server could comprise one or more servers. Also, it could become an application-server like Gunicorn. In any of these scenarios the request will originate from the web in general. In the majority of cases, your request is transmitted directly to a web server with the information the user seeks. Reverse proxy acts as an intermediary and isolates the webserver from direct communications with the internet.



From the perspective of a user the experience of interacting with a reverse proxy is no different than communicating with an internet server direct. It's basically the same, but the user is unable to see the distinction. The client requests the resource, and is then provided with it, with no additional configuration required by the client.



Reverse proxies provide features like:




  • Centralized security for web servers.


  • The direction of traffic coming in by implementing rules that you establish.


  • New functionality added for caching.



While centralized security can be an advantage of both reverse and forward proxy servers. Reverse proxies provide this service only to the layer that is the webserver and not to the client layer. instead of the maintenance of firewalls in the web server layer, which might contain many servers with different configurations, the majority of firewall security is targeted at the reverse proxy layer. Furthermore, the removal of the burden of interacting with a firewall and communicating with requests from clients via web servers allows them to concentrate solely on addressing the needs of their customers.



In the event of multiple servers operating with a reverse-proxy the reverse proxy also handles the direction that requests are directed towards which servers. Multiple web servers could be operating from the same host, providing different types of resources or a combination of the two. They can use the HTTP protocol just like a conventional web server, however they may also be able to be equipped with application server protocols like FastCGI. It is possible to set up reverse proxy servers that redirect users to a particular server based on the service required, or to a set of rules for the amount of traffic.



Reverse proxies may also benefit by being placed on top of web servers, as they provide caching capabilities. The large static resources can be configured by using caching rules in order to avoid having to contact web servers each time you request. Some solutions allowing you to directly serve static content without having to connect with the webserver even once. Additionally reverse proxy solutions are capable of handling the compression of these files.



The well-known Nginx web server also functions as a highly regarded reverse proxy solution. Although Apache is also a reverse proxy solution it is not the only one. Apache web server does have reverse proxy features however, it's a separate feature available to Apache as opposed to Nginx was originally designed to and is focused upon the feature of reverse proxy.



Differentiating Forward Proxy from reverse Proxy Use



Because "forward" as well as "reverse" are associated with the notion of directionality, and inaccurate comparisons to "incoming" and "outgoing" traffic, the labels can be confusing since both types of proxy services handle both requests and replies. The best method to distinguish between forward and reverse proxy is to consider the needs of the application that you are developing.



A reverse proxy is a useful tool when you are developing a solution that can deliver web-based apps over the internet. They serve as your web servers during any interaction on the internet.



Forward proxy is useful when put before users for personal use or in the workplace. They represent your client's activity whenever you interact on the internet.



The practice of segregating by use case, instead of using only common naming conventions can ensure that you don't get confused.



Conclusion



This article provides the definition of a proxy, focusing on the two major types, which are the forward proxy and reverse proxy. Practical examples of how to use them as well as a review of the advantageous features were used to differentiate between reverse and forward proxy.
