It is an proxy commonly referred to as proxy server software that sits as an intermediary between the client and server on the web. Without the use of a proxy, a user could send a request for a resource directly to a server and it would serve the requested resource directly to the user. It's not hard to understand and implement the addition of proxies can bring advantages such as improved performance, privacy, security, and more. In addition to providing a layer of security, proxies serve as a security barrier on the internet, separating clients and servers.




The general set of server hardware as well as the software to install proxy servers is commonly referred to as proxy servers. This article will concentrate on proxies commonly referred to as software, and also in relation to web servers. The article will provide an explanation of the two main types of proxies, which are forward proxy and reverse proxy. forward proxy and reverse proxy. reverse proxy. Each has a distinct use scenario, which is often misunderstood due to the overlapping naming convention.




This article will give you an understanding of nature of proxies and subtypes are, as well as how they work in the common configurations. In the article you'll learn how to identify the circumstances that using proxies can be advantageous, and choose the best option between forward and reverse proxy in each circumstance.



Understanding Forward Proxies



In another way forward proxy also called an open proxy acts as the representative of a client who wants to send requests through the internet to an origin server. In this case the client's attempts to send requests made by the client will be forwarded via the forward proxy. In this case the forward proxy acting instead in the place of the customer will review the request. First, it must determine whether the client is authorized to accept requests from this particular forward proxy. It will then either deny the request or forward it to its origin server. The client doesn't have a an internet connection directly; it can only connect to the internet that forward proxy allows it to connect to.




The most common reason to utilize forward proxy servers is to gain greater privacy or security on the internet. Forward proxy makes use of the internet in lieu of a client, and may use a different IP address to the client's initial IP address.




Based on the way it's setup, and how it is configured forward proxy could provide various features as well as the capability to:




Do not be a victim of ad tracking.


Circumvent surveillance.


Find restrictions based on your geographic area.




Forward proxies are also used in systems that offer centralized security and access based on user permissions like at work. If all traffic on the internet flows through an open forward proxy layer administrators could allow access only to specific users who are filtered by the common firewall. Instead of having firewalls installed on the client layer that could contain various devices with different settings and users and environments A firewall could be set up at the forward proxy layer.




It is important to note that forward proxy servers have to be manually set up for use before they can be used, while reverse proxy servers are able to be not recognized by clients. Based on whether or not the IP address of the client has been transferred to the origin server through the forward proxy privacy and anonymity may be provided or rendered more transparent.




There are many possibilities to explore for forward proxy options:




Apache The Apache is a popular open-source webserver that provides forward proxy capabilities.


Nginx: Another well-known open-source webserver with forward proxy capabilities.


Squid: A free forward proxy that uses the HTTP protocol. Squid doesn't include the full web server. You can check out our guide on the best method of creating Squid proxy to allow private connections on Ubuntu 20.04.


Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP which makes it more suited for scenarios such as peer-to-peer communication. It is also possible to learn how to setup an Dante proxy to connect privately on Ubuntu 20.04



Understanding Reverse Proxies



A reverse proxy functions to act as an agent of a web server, handling any requests that come in from customers on behalf of the server. The web server could be comprised of one server or a number of servers. Additionally, it can serve as an application server, like Gunicorn. In both cases, the request may be made by a client via the internet at large. Normally, this request will be sent directly to the website server with the resources that the user is in need of. In contrast, a reverse proxy functions as an intermediary that isolates your website server from any interactions with the open internet.




From the perspective of a user, the experience of using reverse proxy isn't different than communicating directly with your webserver. It is functionally identical and users can't tell the difference. Client requests resources and receives it without any additional configuration from the user.




Reverse proxies provide functions like:




Security centralized for web servers.


Directing traffic according to the rules you set up.


New caching functionality has been added.




While central security is a benefit of both reverse and forward proxy platforms, reverse proxy providers this service only to the server layer and not to the layer that clients use. In lieu of maintaining firewalls on Web server layers which could contain multiple servers that have different configurations, the majority of firewall security can be centered in the reverse proxy layer. In addition eliminating the burden of interfacing with a firewall as well as communicating with clients' requests away from web servers allows them to concentrate on meeting the requirements of their customers.




If there are multiple servers that are in a reverse proxy,, the reverse proxy also is responsible for deciding which requests go to which server. There could be multiple web servers providing the exact identical service, with different types of resources or a mix of both. They may use the HTTP protocol just like a standard web server, but can also be outfitted with protocols for application servers like FastCGI. A reverse proxy can be used to direct clients to specific servers depending on the kind of resource they are seeking, or to follow specific rules regarding traffic load.




Reverse proxies may also benefit from their location on top of web servers, by providing the capability to store information. Large static files can be configured with caching policies to avoid the web server from being hit with every request. Some applications allow users to serve static content directly without ever touching the server. Furthermore reverse proxy has the capability of compressing these assets.




The well-known Nginx webserver is a reliable reverse proxy option. It is true that the Apache web server comes with a reverse proxy, however it's a distinct function of Apache but Nginx was originally designed to focus specifically on the reverse proxy feature.



Differentiating Forward Proxy from Reverse Proxy Use. and Reverse Proxy Utilization



Since "forward" as well as "reverse" are associated with directionality, and can lead to misleading comparisons with "incoming" and "outgoing" traffic. The labels can be confusing because both types of proxies are capable of handling requests as well as responses. The best way to distinguish between reverse proxy as well as forward proxies would be to look at the requirements of the application that you are developing.




Reverse proxy is a crucial aspect to consider when developing a solution that can provide web-based applications over the internet. They function as servers whenever you connect to the internet.




Forward proxy can be useful when it is placed in front of users for personal usage, or even in a commercial setting. They represent your clients whenever you use the internet.




The use case-based differentiation rather than focusing exclusively on similar names can help avoid confusion.



Conclusion



The article explained what a proxy is along with the two types of them: reverse and forward proxy. Application scenarios that can be used in practical situations and a review of the most useful features were used to differentiate between reverse and forward proxies.
