It is an proxy is also referred to as proxy server, which is a software that acts in the middle between client and server over the internet. Without proxy, a user could send a request for a resource directly to a server and it would serve direct to users who requested the resource. Although this method is easy to understand and implement but adding proxies offers advantages in the form of greater performance as well as privacy, security and many more. In addition to being able to pass over, the proxy acts as a guardian for the internet, separating clients and servers.




There is a general consensus this: the mix of hardware for servers with the software that is installed to make proxy connections is commonly referred too as proxy servers. For this post, we'll concentrate on proxies that are typically described in terms of software as well as those that are employed to work in conjunction with web servers. This article will provide a detailed breakdown of two types of proxies such as a forward proxy and reverse proxy. reverse proxy. Each is unique in its use that is frequently confused due to the similar namesake convention.




This article will provide you with some understanding about what proxy services are, and subtypes they have, and what ways they can be useful for common setups. By reading this article, you'll be able to discern the scenarios in which a proxy is useful, and then decide the best reverse or forward proxy in any given situation.



Understanding Forward Proxies



The forward proxy also referred to as the open proxy is the representative of a client who is trying to route an internet request to an origin server. In this situation it is the case that all requests from the client will be directed via this forward proxy. In this situation, the forward proxy in lieu of the client will review the request. It will first will determine if the client is allowed to forward requests through this specific forward proxy. It will then decide whether to refuse the request or send it back to its origin server. It isn't able to connect directly via the Internet. It is only able to access the information the forward proxy allows it to access.




A common reason for using forward proxies is for greater privacy or security online. A forward proxy connects to the internet as a personal client, and during this way, it could use another IP address in opposition to the IP address that is used by the client.




Based on the way it was configured in the past forward proxy servers could give you a variety of options, allowing you to:




Stay clear of tracking ads.


Circumvent surveillance.


Find restrictions based on your place of residence.




Forward proxies are also used in systems that offer central security and permit-based access, like in a workplace. In the event that all internet traffic flows through an open forward proxy layer, the administrator is able to grant only a few clients access to the internet that is blocked by a standard firewall. Instead of maintaining firewalls for the client layer that can include multiple machines with different user and environment the firewall can be set up on the layer that forwards proxy traffic.




Remember that forward proxies have to be set up manually for be used, while reverse proxies are often ignored by clients. Based on the fact that clients' IP addresses are sent to the origin server via the forward proxy, privacy and anonymity can be made transparent.




There are a myriad of choices to think about for forward proxies:




Apache A well-known, open-source web server that provides forward proxy features.


Nginx is another well-known open-source web server with forward proxy functionality.


Squid is an open source forward proxy that makes use of an HTTP protocol. It doesn't provide an entire web server service. Check out our article on the most efficient way to setup Squid proxy for private connections in Ubuntu 20.04.


Dante forward proxy that makes use of the SOCKS protocol rather than HTTP which makes it more suitable for scenarios like peer-to -peer traffic. It's also a good idea to check out how to configure a Dante proxy to allow private connections in Ubuntu 20.04



Understanding Reverse Proxies



Reverse proxy is a representative of a web server which handles incoming requests from customers on its behalf. The web server may represent a single or several servers. It could also serve as an app server, such as Gunicorn. In any of these scenarios, a request could come in via a user on the internet in general. The majority of the time the request will be directed directly to the web server, along with the information the user is looking for. A reverse proxy is a intermediary and isolates your server from interactions with the internet.




From a client's perspective from a client's perspective reverse proxy is not different from communicating with the webserver in direct communication. It's the same thing, and the client can't discern the difference. Client requests resources, and then receives it, without any additional configurations required for the end user.




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




Centrally secured for Web Server Layer.


Sending traffic to be directed in accordance with rules you set up.


Additional functions for caching.




While central security is a benefit of both reverse and forward proxy solutions, reverse proxy provides this benefit only to the server layer, and not to the client layer. Instead of maintaining firewalls in the layer of web servers that may contain multiple servers with various configurations, the majority of firewall security resides on the reverse proxy layer. In addition, the removal of the requirement of working with firewalls as well as communicating with requests from clients far from web servers allows firewalls to focus on the needs of their customers.




If there are multiple servers behind a reverse proxy, the reverse proxy also takes care of how requests are routed on which server. There could be multiple web servers running from the exact same computer and serving various kinds of resources or a combination of the two. They can be using the HTTP protocol as a conventional web server. They can also use applications server protocols such as FastCGI. You can set up reverse proxy that directs users to specific servers based on the kind of resource they are searching for, or follow certain rules to manage traffic load.




Reverse proxies also profit by their position before web servers by delivering the ability to cache. Large static assets are able to be configured using caching rules to prevent the web server from being hit on every request, with certain solutions giving the option to directly serve static assets without having to connect to the web server at all. Furthermore, reverse proxy could be able to handle compression of these assets.




The famous Nginx web server is also an acknowledged reverse proxy provider. Although the Apache web server, it is equipped with reverse proxy features however, it's a separate feature that is available for Apache however Nginx was originally designed and specifically designed for reverse proxy functionality.



Differentiating Forward and Reverse Proxy Utilizing Differentiation of Forward Proxy and Reverse Use



Since "forward" as well as "reverse" have connotations of directionality, as well as false distinctions between "incoming" as well as "outgoing" traffic These labels can be confusing as both kinds of proxies can manage requests and responses. An alternative method to differentiate between reverse and forward proxy is to look at the specifications of the application you're developing.




A reverse proxy could be helpful in the development of a method to offer web-based services over the internet. They act as your servers when you interact with the internet.




Forward proxy are beneficial when they are used by the client for personal use or in a workplace setting. They represent your client traffic when you interact with the internet.




A distinction based on usage cases instead of focusing exclusively on similar naming conventions can help you avoid confusion.



Conclusion



This article clarifies the meaning of a proxy that includes two main kinds: the forward proxy and the reverse proxy. Practical application scenarios and a look at advantageous features were used to differentiate forward proxies and reverse proxy.
