It's proxy or proxy server. proxy or proxy server. is a server software program that acts as an intermediary between clients and servers on the internet. With no intermediaries, a user can send a request or resource to the server directly and the server would then serve direct the resource requested to the customer. While this procedure is easy to understand and implement using proxy servers, it could provide advantages such as more performance and privacy, security and much more. As a layer of pass-through, the proxy functions as a security protector of the internet between the servers and clients.




In general, the mix of the server hardware as well as software to install proxy servers is commonly referred to as proxy servers. In this post, we'll focus on proxies typically understood as software, and those that are used in conjunction with web servers. This article will give a detailed breakdown of the two main types of proxies: forward proxy and a reverse proxy. reverse proxy. Each kind of proxy has its own specific usage scenario, which is often misunderstood due to the naming conventions that are similar.




This article will provide you with some understanding about what proxies and their subtypes are, and what they can do for most common configurations. Through this article, you will be able to identify the scenarios where an effective proxy could be useful, and select the best option between reverse and forward proxy for any particular situation.



Understanding Forward Proxies



In other words forward proxy, is also known as an open proxy is a representative of the client which is attempting to send requests via the internet to an origin server. In this scenario the entire request to send it from the client will be sent by the forward-proxy. In this case, the forward proxy acting in place of the client will review the request. It is the first thing to determine what authorization the user has to send requests to this particular forward proxy. The forward proxy will then deny this request and forward it to the server originally. The client is unable to connect directly to the internet. It is only able to access what the forward proxy allows the client access.




The most common reasons for forward proxy is greater privacy or anonymity online. A forward proxy can be utilized to access the internet in place of a client and in that process it may use a different IP address to the IP address that was originally assigned to the client.




Based on the way it was configured in the past forward proxy servers may provide a variety of functions and permit you to:




Do not be a victim of ad tracking.


Circumvent surveillance.


You can identify restrictions based upon your geolocation.




Forward proxies are also employed in security systems that require centralized and permission based access like at work. If all internet traffic flows through an open forward proxy layer administrators can allow access only to specific users to the internet. This is blocked by a standard firewall. Instead of putting firewalls in place for the client layer which could comprise a range of computers with different environments and users and environment, a firewall may be placed at the intermediate layer.




It is important to note that forward proxies must be manually set up to function, but reverse proxies are not noticed by the client. Based on whether an IP address from a client is sent to the source server via the forward proxy, privacy and anonymity could be granted or not noticed.




There are many options to look into for forward proxies:




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


Nginx: Another popular open-source web hosting server that has forward proxy functions.


Squid is an open source forward proxy that makes use of an HTTP protocol. It doesn't provide an entire web server service. We have a tutorial on how to configure Squid proxy for private connection to Ubuntu 20.04.


Dante Forward Proxy that utilizes the SOCKS protocol instead of HTTP and is more suited to cases like peer-to-peer connections. You can also examine how you can configure a Dante proxy to connect privately in Ubuntu 20.04



Understanding Reverse Proxies



Reverse proxy functions as an agent for web servers, which handles incoming requests by clients on behalf of. This web server may consist of a single server or multiple servers. It may also act in the role of an application server, such as Gunicorn. In any of these situations the request may come from a user through the internet in general. The majority of the time it will be routed straight to the web server hosting the information the user needs. Reverse proxy is an intermediary, separating Web servers from direct communication with the internet.




From a client's viewpoint, which is from a user's point of view using reverse proxy isn't different from connecting directly to your webserver. It's the same thing, however clients can't tell the distinction. The customer requests an item and receives it without any additional configuration needed to be done by the client.




Reverse proxy proxies may offer options, such as:




A central layer of security that protects the server.


Controlling traffic coming inbound according to rules that you can set up.


A new feature to cache is now available.




While central security is a benefit of both reverse and forward proxy service, reverse proxies provide this service to this level of an internet server rather than the client layer. instead of the maintenance of firewalls in the layer of web servers which may include multiple servers with different configurations, the majority of firewall security is focused on this layer. In addition, the absence of interfacing with firewalls as well as interacting with the requests of clients from web servers allows them to concentrate solely on meeting the needs of their customers.




If there are several servers running through reverse proxy, the reverse proxy also determines how requests are routed on which server. A number of web servers could be offering the same content but each serving different types of resources, or some mix of them. They may be using the HTTP protocol similar to a traditional web server, however, they may also include protocols for applications such as FastCGI. You can also configure a reverse proxy to redirect the clients towards specific servers in accordance with the service requested or to follow specific rules regarding traffic load.




Reverse proxies may also benefit from their positioning before web servers by supplying the ability to cache data. Large static files can be set with caching rules to stop the web server from being hit with every request Certain solutions offer the possibility of providing static files directly without touching the server in any way. Furthermore, the reverse proxy could handle the compressing these assets.




The popular Nginx web server is an extremely popular reverse proxy solution. Although Apache is also a reverse proxy solution, the Apache webserver is also equipped with reverse proxy function as an added option for Apache in contrast to Nginx was initially designed for and specifically focused on reverse proxy capabilities.



Differentiating Forward Proxy and Reverse Proxy Use Situations



Since "forward" along with "reverse" are ascribed to a sense of directionality, and a false comparison with "incoming" as well as "outgoing" traffic These labels can confuse because both types of proxies handle both responses and requests. The best way to distinguish between reverse and forward proxy services is to consider the requirements of the application that you are developing.




A reverse proxy is useful in the design of a solution that can serve web-based applications via the internet. They represent your web servers in all interactions on the web.




A forward proxy can be helpful when placed in front of client traffic for personal use or for work. They represent the traffic of your clients when you use the internet.




Differentiating by case of use instead of focusing on the similar naming conventions can help in eliminating confusion.



Conclusion



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