Genius! How To determine If You need to Really Do Proxy Sites

February 23, 2024

A proxy, also called a proxy server. It is software that acts as an intermediary between a client and server over the internet. Without a proxy, a client will send a request to resources directly to the server and it would then serve the resource directly back towards the customer. This method is simple to comprehend and implement, however, adding proxy servers can offer benefits including improved speed and privacy, security and more. In addition to providing passing through, the proxy acts as a security guardian of the internet between clients and servers.

The combined system of server hardware coupled with the software for proxy installation is often described as proxy servers. This article will discuss proxy servers that are typically classified as software, as well as in relation to web servers. We will discuss of two kinds of proxies. One being forward proxy and the other being a forward proxy and the reverse. reverse proxy. Each type has its own application and is often confused due to the similar namesake convention.

This article will give you an idea of the types of proxies and subtypes, as well as their importance for the common setups. If you read the article carefully, you’ll be able discern situations in which using proxies can be advantageous and choose the most appropriate option between forward proxy and reverse proxy based on the situation.

Understanding Forward Proxies

Forward proxy, also referred to as the open proxy serves as the representative of a client who wishes to make an internet-based request to an the server which originated it. In this case, all attempts to make requests through the client’s end will instead be directed directly to the forward proxy. The forward proxy, instead of the client, will examine the request. It will first verify if the client is allowed to receive requests from this specific forward proxy. It will then deny any request or forward it to its origin server. The client does not have an internet connection directly; it can only reach what forward proxy permits it to access.

The most popular reason to use forward proxies is increased privacy or anonymity on the internet. Forward proxy connects to the internet as clients, and as such, it could use an IP address that is different from the IP of the client.

Depending on the way it’s set up, the forward proxy can provide a variety of functions in addition to the ability to:

  • Beware of Ad-trackers.

  • Circumvent surveillance.

  • Find restrictions based on your location.

Forward proxies can also be used in systems that provide centralized security as well as access to users based on permissions, for instance at work. All internet traffic can pass through a forward proxy, an administrator is capable of allowing only certain clients access to the internet using a common firewall. Instead of having firewalls in place for the client layer, which could include multiple machines with varying settings and users and environments the firewall is put in an forward proxy layer.

It is essential to note to set forward proxy preferences must be manually setup to allow the forward proxy to function in order to use them and reverse proxy servers are unable to be noticed by the user. Based on an IP address belonging to the user is transmitted to the server from which it originated through the forward proxy, the privacy and security can be granted or not.

There are numerous options to think about when it comes to forward proxy choices:

  • Apache An open source well-known web server that has forward proxy functions.

  • Nginx Another well-known open-source web hosting server with forward proxy capabilities.

  • Squid is a free forward proxy that uses it’s HTTP protocol. It’s not the full webserver system. We recommend our article on the most efficient method to set up Squid proxy for secure connections within Ubuntu 20.04.

  • Dante Forward proxy that makes use of the SOCKS protocol instead of HTTP and HTTP, making it more suited to cases like peer-to -peer traffic. It is also possible to learn how to configure Dante proxy for connection to private networks in Ubuntu 20.04

Understanding Reverse Proxies

Reverse proxy acts as an intermediary for web servers, and is able to handle requests from customers for the web server. Web servers can function as a single server, or as a series of servers. Additionally, it can be an application server such as Gunicorn. In all cases, the request for an application comes from a user via the internet at large. Most of the time, the request will directly go to the web server that hosts the content that the client is looking for. A reverse proxy acts as a middleman to protect your server from interaction to the open internet.

From a consumer’s point perspective, using reverse proxy isn’t different from communicating with your webserver directly. It is functionally similar, however the client can’t discern the distinction. The client requests an item and receives it, without requiring any additional configuration for the end user.

Reverse proxy providers provide features like:

  • The web server is secured centrally.

  • The sending of traffic according to rules you set.

  • A new feature for caching has been added.

While centralized security is an advantage of both forward and reverse proxy, reverse proxy applications apply this only for just the Web server layer and not to the client layer. instead of maintaining firewalls on Web server layers which may include multiple servers with different configurations, the bulk of firewall security is aimed at the reverse proxy layer. Additionally, removing the burden of interfacing with firewalls and responding to clients’ requests off of web servers enables them to concentrate on providing resources.

In the case of multiple servers existing with a reverse-proxy, the reverse proxy is also accountable for deciding which requests are directed to which server. There could be multiple web servers operating from the same host, all serving different types of resources or a combination of the two. They could be using the HTTP protocol similar to a conventional web server. They can also include application server protocols like FastCGI. You can also set up a reverse proxy to route the clients towards specific servers depending on the service being requested, or to observe certain traffic load rules.

Reverse proxies are also able to take advantage of their placement on top of web servers with the help of caching. The large static files can be configured with caching rules to avoid the web server from being hit with each request, with some solutions even allowing you to provide static files in a direct manner without linking to the web server in any way. Additionally, reverse proxy can manage the compression of these assets.

The popular Nginx web server is a wildly popular reverse proxy service. However, the Apache web server comes with the reverse proxy function as an added feature that is available for Apache however Nginx was designed initially for and is specifically focused on reverse proxy functions.

Differentiating Forward Proxy from Reverse Proxy Use Cases

Since “forward” along with “reverse” are both associated with the notion of directionality and also inaccurate comparisons to “incoming” and “outgoing” traffic. These labels can be confusing, because both types of proxies can be used to manage requests and responses. Another method of separating between forward and reverse proxy servers would be to study the requirements of the application that you’re developing.

Reverse proxy is an effective tool when you are creating a solution for serving websites on the internet. They represent your web servers during any interaction through the Internet.

Forward proxy is a great tool to have facing clients for personal use or in a business environment. They represent your client traffic when you are on the internet.

A distinction that is based on the use rather than using the standard names can help in avoidance of confusion.


The article explained what a proxy is along with two types being the reverse proxy and forward proxy. Examples of how to use them and a discussion of the most beneficial features was used to differentiate forward proxies from reverse.
