"proxy" refers to a software "proxy" means the idea of a proxy often referred to as a proxy server is software that functions in the role of intermediary between client and server on the internet. Without a proxy, a client can send a request for an online server, and the server would serve an item directly for the client. While this is a simple method to understand and use, proxies can provide advantages such as more performance as well as security and privacy and so on. As a pass-through layer the proxy functions as a guardian to the internet between users and servers.




In general, the system of server hardware that is paired with the software for proxy installation is often known as proxy servers. This article will focus on proxy servers that are usually described as software and specifically, in relation to servers for web. This article will give a synopsis of the two main types of proxies, which is forward proxy and reverse proxy. forward proxy and reverse proxy. reverse proxy. Each type has its own usage scenario, which is often misinterpreted due the overlapping terminology.




This article will give you an idea of what proxies as well as their subtypes and ways in which they can be beneficial in a variety of configurations. If you read this article you'll be able to recognize the circumstances in which the use of proxies is beneficial and identify the best alternative between reverse proxy and forward proxy in any given situation.



Understanding Forward Proxies



Forward proxy is also known in the context of an open proxy serves as the representative of the client trying to relay an internet request to a source server. In this scenario, every attempt to send requests by the user will be sent via an forward proxy. The forward proxy, acting in place of the client will review the request. Then, it will determine whether or not the client is able to transmit requests through this particular forward proxy. It will then orally reject a request and send it back to its server that originated the request. The client is unable to have direct connection with the Internet. It is only able to connect to what the forward proxy allows for it to reach.




The primary reason for people to utilize forward proxy servers is to gain greater security or privacy when surfing the internet. A forward proxy can be used to access the internet, instead of clients, and in this way, it utilizes an alternative IP address to the original IP address of the client.




Based on the way it's configured, and how it is configured forward proxy can offer a variety of features, allowing you to:




Beware of ads-trackers.


Circumvent surveillance.


You will be able to identify any limitations based on your geographic area.




Forward proxies can also be used to secure systems that are centralized and access based on permissions, like at a workplace. In the event that all internet traffic is routed through a common forward proxy layer, an administrator might restrict access for just a small number of users to the internet, which is filtered by an common firewall. Instead of establishing firewalls for the client layer which could be used by multiple computers with different environments and types of users you can have a firewall at the front proxy layer.




Be aware that forward proxy servers must be manually configured for use in order to be used, whereas reverse proxies can be obfuscated by clients. Based on whether an IP address belonging to the user is relayed to the server of origin by the forward proxy privacy and anonymity can be granted or denied.




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




Apache An open-source, well-known web server with forward proxy capability.


Nginx: Another popular open-source webserver that includes forward proxy capabilities.


Squid: A free forward proxy that uses an HTTP protocol. It's not included with the whole web server. Check out our instructions on how to set up Squid proxy to allow private connections in Ubuntu 20.04.


Dante Forward proxy that utilizes the SOCKS protocol instead of HTTP which makes it more suitable for use instances such as peer-to -peer traffic. You may also want to check out how to configure Dante proxy to permit private connections with Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy acts as an agent for a web server that handles customer requests for its behalf. It could represent one or more servers. Also, it could serve as an app server such as Gunicorn. In any case, a request would come through the internet generally. The request is typically directed directly to the web server hosting the information the client is in need of. Instead, a reverse proxy acts as an intermediary, and separates Web servers from any direct interactions with the web's public.




From the viewpoint from the client's perspective the process of utilizing reverse proxy is the same than interacting with the server on its own. It's exactly the same however the client cannot discern the difference. Client requests the resource and then receives it, without any additional configuration needed for the customer.




Reverse proxies provide features like:




The server for the web is secure centrally.


The direction of traffic coming in is by rules you have set.


A new feature for caching is now available.




While central security is a benefit offered by both forward and reverse proxy servers. Reverse proxy providers offer this feature to only the server layer but not the client layer. In lieu of maintaining firewalls at the server level that could include several servers, each with various configurations, the bulk of firewall security is concentrated at the reverse proxy level. In addition, removing the burden of working with firewalls and connecting with client requests away from web servers enables the firewall to concentrate on providing the requirements of their customers.




When there is a multitude of servers being located within a reverse proxy this reverse proxy will be also responsible for how requests are routed at which server. Many web servers may be providing the same service, but offering various kinds of resources or a combination of both. These servers may use the HTTP protocol to serve as a standard web server, but can also include protocols for application servers like FastCGI. You can also configure reverse proxy settings to send users to specific servers depending on the requested resource, or to adhere to certain guidelines for traffic load.




Reverse proxies can also benefit from their position prior to web servers by offering caching capabilities. Large static assets can be configured with caching rules in order to ensure that web servers are not hit each time you request. There are solutions allowing users to serve static assets without connecting directly to web servers in any form. In addition, the reverse proxy is able to compress these assets.




The well-known Nginx web server functions as an effective reverse proxy service. While Apache can also be a reverse proxy solution it is not the only one. Apache web server comes equipped with a reverse proxy feature which is an additional feature available to Apache however Nginx was initially designed to specifically focus on reverse proxy features.



The difference in Forward Proxy and Reverse Proxy Use Situations



Since "forward" and "reverse" are associated with the notion of directionality as well as misleading distinctions between "incoming" and "outgoing" traffic, these labels can be confusing since both types of proxies deal with both requests as well as responses. The best way to distinguish between reverse and forward proxy is to study the specifications of the application that you're creating.




A reverse proxy can be helpful when you're developing a method to connect web-based applications to the internet. They serve as your web servers whenever you interact using the internet.




Forward proxy are beneficial when they are used before customers for your personal use or in a professional setting. They serve as the proxy for your client when you interact with the internet.




Distinguishing by use case instead of focusing on naming conventions that are commonplace can assist you in avoiding confusion.



Conclusion



This article describes the meaning of a proxy with two kinds: forward proxy and reverse proxy. Examples of how to use it and a brief overview of useful features were used to differentiate forward proxies and reverse proxy.
