It is a proxy or proxy server. is a software program for servers which serves as an intermediary between a the server and the client on the internet. Without an intermediary, the user can send a request or resource to the server directly, and the server will serve direct the resource requested to the user. Although this is a simple process to understand and implement using proxy servers, it does offer advantages such as more performance as well as privacy, security and many more. As a pass-through layer, the proxy acts as a security guardian of the internet between the servers and clients.




Generally speaking, the bundled system of hardware for servers and software used to set up proxy installations is commonly referred to by the name proxy servers. In this post, we'll examine proxies commonly referred to as software, and ones that work in conjunction with web servers. We will provide a description of the two major types of proxies: forward proxy and a reverse proxy. reverse proxy. Each kind has its own unique usage scenario, which is often misunderstood due the naming conventions that are similar.




This article will give you an understanding of what proxies and their subtypes are, and what they can accomplish for typical configurations. Through this article, you will be able to identify the situations in which an effective proxy can be beneficial, and choose the correct solution in between reverse and forward proxy to suit your needs in any given situation.



Understanding Forward Proxies



In other words, a forward proxy also known as open proxy open proxy is a representative of the client which is attempting to send a request via the internet to the server from which it originated. In this scenario the entire attempt to send requests by the client will be made by the forward-proxy. In this situation an agent acting on behalf of the forward proxy in instead of the user will review the request. First, it will establish whether the client is authorized to send requests via this particular forward proxy. It then will reject the request and send it back to the original server. The client isn't able to have direct connection to the internet; it can only reach what the forward proxy allows the client access.




The most common uses for forward proxies is to provide greater privacy or security online. A forward proxy can be utilized to connect to the internet in instead of a client and in that process it can use an alternative IP address to the IP address that was originally assigned to the client.




Based on the way it was set up in the past forward proxy servers are able to provide a variety of functions and let you:




Avoid ad tracking.


Circumvent surveillance.


You can determine limitations based on your location.




Forward proxies are also used for security systems that are centralized and allow access based on permissions, such as in the workplace. When all internet traffic passes through a common forward proxy, an administrator is able to grant access only to specific users to the internet, which is filtered by an common firewall. Instead of putting firewalls in place for the client layer, that could be comprised of a variety of computers with different user and environmental settings and environment, a firewall may be placed on the forward proxy layer.




It is important to note that forward proxy servers must be manually set up for use, However reverse proxy will be not noticed by the client. Based on the fact that the address IP of a customer is passed to the original server through an forward proxy. Privacy and anonymity can be granted, or not noticed.




There are several possibilities to investigate for forward proxies:




Apache is an well-known open-source web server, that offers forward-looking proxy features.


Nginx: Another well-known open-source server used for web hosting with forward proxy functions.


Squid is an open-source forward proxy which utilizes an HTTP protocol. This does not include an entire web server. We've got a guide on how you can configure Squid proxy to allow private connections on Ubuntu 20.04.


Dante Forward Proxy that utilizes the SOCKS protocol instead of HTTP and is more suitable for situations like peer-to-peer connections. It is also possible to explore how you can configure a Dante proxy to connect privately using Ubuntu 20.04



Understanding Reverse Proxies



Reverse proxy functions as an agent of web servers, which handles the incoming requests of clients on behalf of. This web server may comprise one server or multiple servers. It could also serve for application servers such as Gunicorn. In any of these situations, a request could come from a client via the internet at large. The majority of the time it will be routed direct to the website hosting the information the user needs. A reverse proxy is a intermediary that separates Web servers from direct interactions with the internet.




From a client's viewpoint, which is a user's viewpoint connecting to reverse proxy isn't different from connecting directly to your webserver. It's the same thing but the client isn't able to tell the distinction. The customer requests an item, and it is delivered with no additional configurations that need to be performed by the client.




Reverse proxy proxy servers can offer some features, including:




A central layer of security that guards the server.


Controlling traffic coming inbound according to rules that you establish.


A new feature for caching is now available.




Central security is an advantage of both forward and reverse proxy solutions, reverse proxies provide this feature to the layer of the internet server rather than clients. instead of maintaining firewalls at the web server layer, which might contain several servers with various configurations, the bulk of firewall security is focused on the reverse proxy layer. Additionally, getting rid of the necessity to interface with firewalls as well as interacting with the requests of clients from web servers enables them to concentrate solely on meeting the needs of their customers.




If there are several servers using a reverse proxy, the reverse proxy also handles the method of routing requests to which server. There are many web servers offering the same content, but each serving different types of resources, or some mixture of the two. They may be using the HTTP protocol like a traditional web server, however, they may include applications server protocols such as FastCGI. You may also set up reverse proxy in order to direct clients to specific servers depending on the requested resource, or to observe certain guidelines for traffic load.




Reverse proxies may also take advantage of their placement before web servers by supplying the ability to cache data. Large static files may be managed using caching rules to prevent the server from getting hit every time a request is made Certain solutions offer the possibility of providing static files without contacting the web server in any way. Furthermore, the reverse proxy could handle the compressing these assets.




The popular Nginx web server is a wildly popular reverse proxy option. While Apache is also a reverse proxy solution, the Apache website server also equipped with reverse proxy functionality, it is an additional option for Apache and is in contrast to Nginx was initially designed for and specifically focused on reverse proxy capabilities.



Differentiating Forward Proxy and Reverse Proxy Use Situations



Because "forward" in addition to "reverse" are ascribed to the notion of directionality and a false comparison with "incoming" or "outgoing" traffic These labels are confusing because both types of proxies manage requests and responses. A better approach to distinguish between forward and reverse proxy services is to consider the needs of the app you're developing.




A reverse proxy is useful in the design of a solution that can provide web-based applications on the internet. They act as your servers in all interactions with the web.




Forward proxy can be useful when used in front of client traffic for personal use or in a work environment. They represent the traffic of your clients whenever you interact on the internet.




Differentiating by use case rather than focusing solely on similar naming conventions can help you in avoidance of confusion.



Conclusion



This article describes what a proxy is with the two primary kinds being forward proxy and reverse proxy. Examples of practical applications and a review of the most useful attributes were used to establish forward proxies as well as reverse proxies.
