A proxy, also known as a proxy can also be referred to as a proxy server. It is software that acts to act as an intermediary for client and server on the internet. If there was no proxy in place, the user would send a request for every resource straight to server, and servers would provide the requested resource directly to the user. This is a simple method to comprehend and use using proxy servers may provide benefits including increased speed, privacy and security, among others. As an additional layer of security proxy servers function as a gatekeeper for the internet between clients and servers.




The consensus is that the hardware for servers, paired with proxy software is often called proxy servers. But, this article will focus on proxies that are traditionally referred to as software, and specifically in relation with web server. We will give a synopsis of the two main kinds of proxy services which are forward proxy and reverse proxy. reverse proxy. Each kind has a distinct use, which could be confusing due to the same namestamp.




This article will provide you with an idea of the what proxies and their subtypes are, as well as their importance for the most common setups. After reading this article you'll understand the situations when you can benefit by a proxy and make the right choice between reverse proxy and forward proxy depending on the situation.



Understanding Forward Proxies



Forward proxy, also known as open proxy, sometimes referred to as open proxy acts as an agent for users who wish to send a request via the internet to a source server. In this instance, any request made by the user will be sent through the forward proxy. A forward proxy in the position of the customer will look into the request. It first decides if the client is authorized to accept requests through this specific forward proxy. It will then either deny requests or send it back to server that originated it. The client will not be capable of having an internet connection directly. it will only be capable of accessing the information that the forward proxy gives its access.




The most frequent applications for forward proxy servers is increased privacy or security on the internet. A forward proxy is able to access the internet in lieu of a specific client and may use a different IP address, in contrast to the IP address that is used by the client.




Depending on how it's been set up, and how it is configured, forward proxy may offer various features that allow you to:




Avoid tracking ads.


Circumvent surveillance.


Find restrictions based on the your location.




Forward proxies are also employed in systems that provide central security as well as permission-based access, such as in a workplace. If all internet traffic is routed through an open forward proxy layer, administrators are able to allow only specific clients access to the internet. The web is controlled by a standard firewall. Instead of putting firewalls on the client layer that could include multiple machines with different settings and types of users, the firewall could be placed the proxy layer that is in front.




Remember that forward proxies must be manually configured for use while reverse proxies could be disregarded by the client. According to the kind of IP address a client is sent to the server which originated it via the forward proxy security and privacy can either be provided or rendered more transparent.




There are many choices to be considered for forward proxy:




Apache is an well-known open-source web server which provides forward proxy capability.


Nginx is another well-known open-source webserver that includes forward proxy capability.


Squid: A free and open forward proxy open source that uses an HTTP protocol. This option doesn't include the entire web server. We recommend you read our article on the best method to set up Squid proxy to permit private connections on Ubuntu 20.04.


Dante is an forward proxy that utilizes the SOCKS protocol instead of HTTP which allows it to be more suitable for scenarios like peer-to-peer connections. It is also possible to learn how to configure an Dante proxy to allow private connections in Ubuntu 20.04



Understanding Reverse Proxies



Reverse proxy is the web server, which handles requests from customers on behalf of the server. It can be used as a single server or a number of servers. Additionally, it can comprise an application server, such as Gunicorn. In any of these instances the request will be made via the web in general. In the majority of cases the request is made directly to the web server, along with the resources the user requires. A reverse proxy functions as an intermediary, separating your web server from communication with the internet's users.




From a consumer's point viewpoint from the perspective of a client reverse proxy use isn't different from connecting directly to an internet server. It's basically the same, but the client isn't able to discern the distinction. The client asks for the resource, and then gets it without any additional configuration needed from the client.




Reverse proxies provide features such as:




A centralized layer of security to protect the server.


Controlling traffic inbound based on rules that you can establish.


A new feature for caching is now available.




Central security is a benefit of both forward and reverse proxy services, reverse proxies give this feature only to only the server layer and not the client layer. Instead of focusing on maintaining firewalls at the server level which could include multiple servers and various configurations, the majority of firewall security can be directed at the reverse proxy layer. Additionally, removing the burden of communicating with firewalls as well as interacting with requests from clients outside of web servers permits them to concentrate solely on delivering the needs of their customers.




In the event of multiple servers being hosted through reverse proxy the reverse proxy handles the routing of requests towards the servers. Multiple web servers could be providing the exact same service, serving different kinds of resources or a mixture of both. They may use an HTTP protocol as a standard web server, but they may also include protocols for application servers like FastCGI. It is possible to set up a reverse proxy to route clients to specific servers based on the request for source, and to follow specific rules regarding traffic volume.




Reverse proxies can also benefit from their positioning before web servers by providing the ability to cache. Large static files can be set with caching rules that prevent from reaching web servers with every request. There are options that provide the possibility of serving static content directly without having to connect with the webserver at all. In addition, reverse proxy is able to handle compressing these assets.




The renowned Nginx web server has become a well-known reverse proxy choice. Although it is true that the Apache web server does have the ability to reverse proxy as an additional feature that is available to Apache However, Nginx was originally designed to and is focused on reverse proxy functionality.



Differentiating Forward Proxy and Reverse Proxy Use Examples



Since "forward" and "reverse" are associated with the perception of directionality, they can lead to false comparisons with "incoming" or "outgoing" traffic and can be confusing since both kinds of proxy servers process requests and respond. A better approach to differentiate between forward and reverse proxy servers would be to study the requirements of the app you're building.




Reverse proxy is a vital element in the creation of a method to run websites on the internet. They act as your servers whenever you connect to the Internet.




Forward proxy is useful for displaying customers to your personal use or in a work environment. The forward proxy is a representation of the information of the customer every time you interact with them on the internet.




A distinction based upon use cases instead of focusing on similar naming conventions can help avoid confusion.



Conclusion



The article clarified meaning of a proxy. There are two types of them being the reverse and forward proxy. Practical applications and an exploration of the beneficial attributes were utilized to identify forward proxies and reverse proxy.
