proxy is also referred to as a proxy is also known as a proxy server software that acts in the middle between client and server on the internet. Without proxy servers, users can send a request for a service directly from the server, and then the server will provide the requested resource directly to the user. Although this method is easy to understand and use, however, the addition of proxy servers could provide advantages in terms of increased speed, privacy and security, and many more. Alongside providing a layer of security it also serves as a guardian for the internet between clients and servers.



The combined bundle of server hardware with an installed software proxy is often referred as a proxy server. In this article, we'll examine proxies commonly categorized as software, and in relation to web server. You will get a breakdown of the two main types of proxies: that is an forward proxy and reverse proxy. reverse proxy. Each one has its own use scenario, which is often not understood due to the common names.



This article will provide you with some understanding about what proxies and their subtypes are, and how they are useful in a range of configurations. In this article, you'll learn to discern the scenarios where a proxy is beneficial, and then make the best option between reverse and forward proxy in any given scenario.



Understanding Forward Proxies



An forward proxy sometimes known as open proxy. An open proxy acts as an agent for a user trying to make a request via the internet to an source server. In this case, every attempt to send a request by the user will be handled by an forward proxy. Forward proxy acting in the place of the client is able to examine the request. It will first determine whether the client has been authorized to receive requests from this particular forward proxy. It will then either deny requests or redirect them to the server that originated it. It's not able to direct connection directly to internet. It only has access to what the forward proxy enables it to access.



A typical use of forward proxy is the requirement for greater security or privacy when surfing the web. Forward proxy connects to the web as a user and during this process, it uses an alternative IP address to the client's IP address.



Based on the way it has been configured according to the method it was set up, forward proxy may provide a wide range of options which allow you to:




  • Beware of tracking ads.


  • Circumvent surveillance.


  • You can spot restrictions based upon your geolocation.



Forward proxies can also be used in systems that give central security and access through permissions, for instance in a workplace. Internet traffic can be routed by an open forward proxy. administrators are able to grant access to specific people to connect on the internet. This is then filtered by the standard firewall. Instead of maintaining firewalls on this layer of client, this can be used by multiple computers that have different settings and users, a firewall could be placed in this forward proxy layer.



Take note that forward proxy servers have to be manually setup to allow their use, however reverse proxies won't be noticed by the user. Based on the fact that the IP address of a user is sent to the origin server via the forward proxy, privacy and anonymity can be granted or hidden.



There are numerous possibilities to think about when it comes to forward proxies.




  • Apache The Apache is a popular open-source web server that offers forward proxy features.


  • Nginx: Another well-known open source web server that has forward proxy functions.


  • Squid is an open source forward proxy that utilizes the HTTP protocol. It doesn't come with the whole web server. We have a step-by-step guide for setting up Squid proxy to allow connection to private networks in Ubuntu 20.04.


  • Dante Forward proxy that uses the SOCKS protocol instead of HTTP and is more suitable for situations such as peer-to-peer traffic. You could also examine how you can install the Dante proxy to allow private connections on Ubuntu 20.04



Understanding Reverse Proxies



Reverse proxy functions as an intermediary to a web server that handles the incoming requests of clients in its place. This server can serve as a single server or a number of servers. It could also comprise an application server, like Gunicorn. In any event, it's possible to receive an inquiry from a client via the web at large. Most of the time, the request would be made directly to the website server that hosts the information the customer is seeking. Reverse proxy serves as an intermediary in order to block your website server from communicating with the internet's users.



From the point of perspective, which is also from a user's perspective, interacting with reverse proxy isn't different from connecting to the server in its own. It's functionally identical to an internet server. The user isn't able to tell the distinction. The client can make a request for the resource and it is then given it, without any additional configuration needed by the user.



Reverse proxies grant features like:




  • Centralized security on webservers.


  • Directing incoming traffic by using rules that you design.


  • Added functionality for caching.



While central security is a benefit of both reverse and forward proxy systems, reverse proxies do this service to servers on the internet but not the layer of clients. instead of having firewalls installed on the layer of web servers that may contain multiple servers with various configurations, the bulk of firewall security is located on that layer called reverse proxy. Additionally, getting rid of the necessity of interfacing with firewalls and interacting with requests from clients that do not use web servers lets them concentrate on providing the needs of their customers.



In the case of multiple servers hosted by reverse proxy the reverse proxy is responsible for directing which requests are routed on which server. Multiple web servers could be providing the exact identical service, however each having different resources, or some combination of the two. They may use the HTTP protocol similar to traditional web servers but can be equipped with application server protocols like FastCGI. It is possible to set up a reverse proxy to direct clients to an individual server depending on the resource they are looking for or to adhere to specific rules regarding traffic load.



Reverse proxy solutions can also profit from their placement on the top of web servers by using caching functionality. Large static files can be arranged by caching rules to prevent hitting web servers every time you request. Some solutions even allowing you to serve static content directly without connecting to a web server at all. Furthermore the reverse proxy can be used to manage compression of these files.



The well-known Nginx web server can also function as a well-known reverse proxy service. While it's certain that Apache web server does have reverse proxy function, it's an additional option. Apache as opposed to Nginx was designed initially to focus on reverse proxy functionality.



Differentiating Forward Proxy from Reverse Proxy Use Cases



Because "forward" and "reverse" are associated with the perception of directionality, and misleading comparisons to "incoming" as well as "outgoing" traffic. The labels can confuse because both types of proxies manage the flow of requests as well as responses. An alternative approach to distinguish between reverse and forward proxy services is to take into account the needs of the application you're developing.



Reverse proxy is an essential aspect when developing a solution to deliver web-based applications to the internet. They are your web servers in any interaction with the internet.



Forward proxy software is useful when they are placed in front of clients for personal use or in a workplace. They can be used to represent your client's traffic as you interact on the internet.



The use case-based distinction instead of focusing only on naming conventions that are commonplace can ensure that you don't get confused.



Conclusion



This article defined what an "proxy" is and the two most common kinds being reverse and forward proxy. Practical applications as well as a summary of beneficial features was used to distinguish forward proxies and reverse proxy.
