6 common use cases of Reverse Proxy scenarios | Packt Hub
Proxy servers are used as intermediaries between a client and a website or online service. By routing traffic through a proxy server, users can disguise their geographic location and their IP address. Reverse proxies, in particular, can be configured to provide a greater level of control and abstraction, thereby ensuring the flow of traffic between clients and servers remains smooth.
This makes them a popular tool for individuals who want to stay hidden online, but they are also widely used in enterprise settings, where they can improve security, allow tasks to be carried out anonymously, and control the way employees are able to use the internet.
What is a Reverse Proxy?
A reverse proxy server is a type of proxy server that usually exists behind the firewall of a private network. It directs any client requests to the appropriate server on the backend. Reverse proxies are also used as a means of caching common content and compressing inbound and outbound data, resulting in a faster and smoother flow of traffic between clients and servers. Furthermore, the reverse proxy can handle other tasks, such as SSL encryption, further reducing the load on web servers.
There is a multitude of scenarios and use cases in which having a reverse proxy can make all the difference to the speed and security of your corporate network. By providing you with a point at which you can inspect traffic and route it to the appropriate server, or even transform the request, a reverse proxy can be used to achieve a variety of different goals.
Load Balancing to route incoming HTTP requests
This is probably the most familiar use of reverse proxies for many users. Load balancing involves the proxy server being configured to route incoming HTTP requests to a set of identical servers. By spreading incoming requests across these servers, the reverse proxies are able to balance out the load, therefore sharing it amongst them equally.
The most common scenario in which load balancing is employed is when you have a website that requires multiple servers. This happens due to the volume of requests, which are too much for one server to handle efficiently. By balancing the load across multiple servers, you can also move away from an architecture that features a single point of failure. Usually, the servers will all be hosting the same content, but there are also situations in which the reverse proxy will also be retrieving specific information from one of a number of different servers.
Provide security by monitoring and logging traffic
By acting as the mediator between clients and your system’s backend, a reverse proxy server can hide the overall structure of your backend servers. This is because the reverse proxy will capture any requests that would otherwise go to those servers and handle them securely. A reverse proxy can also improve security by providing businesses with a point at which they can monitor and log traffic flowing through their network.
A common use case in which a reverse proxy is used to bolster the security of a network would be the use of a reverse proxy as an SSL gateway. This allows you to communicate using HTTP behind the firewall without compromising your security. It also saves you the trouble of having to configure security for each server behind the firewall individually.
A rotating residential proxy, also known as a backconnect proxy, is a type of proxy that frequently changes the IP addresses and connections that the user uses. This allows users to hide their identity and generate a large number of requests without setting alarms off.
A reverse rotating residential proxy can be used to improve the security of a corporate network or website. This is because the servers in question will display the information for the proxy server while keeping their own information hidden from potential attackers.
No need to install certificates on your backend servers with SSL Termination
SSL termination process occurs when an SSL connection server ends, or when the traffic shifts between encrypted and unencrypted requests. By using a reverse proxy to handle any incoming HTTPS connections, you can have the proxy server decrypt the request, and then pass on the unencrypted request to the appropriate server.
Taking this approach offers practical benefits. For example, it eliminates the need to install certificates on your backend servers. It also provides you with a single configuration point for managing SSL/TLS. Removing the need for your web servers to undertake this decryption means that you are also reducing the processing load on the server.
Serve static content on behalf of backend servers
Some reverse proxy servers can be configured to also act as web servers. Websites contain a mixture of dynamic content, which changes over time, and static content, which always remains the same. If you can configure your reverse proxy server to serve up static content on behalf of backend servers, you can greatly reduce the load, freeing up more power for dynamic content rendering. Alternatively, a reverse proxy can be configured to behave like a cache. This allows it to store and serve content that is frequently requested, thereby further reducing the load on backend servers.
URL Rewriting before they go on to the backend servers
Anything that a business can do to easily to improve their SEO score is worth considering. Without an investment in your SEO, your business or website will remain invisible to search engine users. With URL rewriting, you can compensate for any legacy systems you use, which produce URLs that are less than ideal for SEO. With a reverse proxy server, the URLs can be automatically reformatted before they are passed on to the backend servers.
Combine Different Websites into a Single URL Space
It is often desirable for a business to adopt a distributed architecture whereby different functions are handled by different components. With a reverse proxy, it is easy to route a single URL to a multitude of components. To anyone who uses your URL, it will simply appear as if they are moving to another page on the website. In fact, each page within that URL might actually be connecting to a completely different backend service. This is an approach that is widely used for web service APIs.
To sum up, the primary function of a reverse proxy is load balancing, ensuring that no individual backend server becomes inundated with more traffic or requests than it can handle. However, there are a number of other scenarios in which a reverse proxy can potentially offer enormous benefits.

A proxy server is a go‑between or intermediary server that forwards requests for content from multiple clients to different servers across the Internet. A reverse proxy server is a type of proxy server that typically sits behind the firewall in a private network and directs client requests to the appropriate backend server. A reverse proxy provides an additional level of abstraction and control to ensure the smooth flow of network traffic between clients and servers.
Common uses for a reverse proxy server include:
Load balancing – A reverse proxy server can act as a “traffic cop, ” sitting in front of your backend servers and distributing client requests across a group of servers in a manner that maximizes speed and capacity utilization while ensuring no one server is overloaded, which can degrade performance. If a server goes down, the load balancer redirects traffic to the remaining online servers.
Web acceleration – Reverse proxies can compress inbound and outbound data, as well as cache commonly requested content, both of which speed up the flow of traffic between clients and servers. They can also perform additional tasks such as SSL encryption to take load off of your web servers, thereby boosting their performance.
Security and anonymity – By intercepting requests headed for your backend servers, a reverse proxy server protects their identities and acts as an additional defense against security attacks. It also ensures that multiple servers can be accessed from a single record locator or URL regardless of the structure of your local area network.

Proxies mask your real IP address with that of a proxy server’s IP address. However, proxies are of different types based on the location of proxy servers’ IPs. Residential proxies hide your real IP address with an IP address that comes from an original physical location rather than a data center. The best part about residential proxies is that they are challenging to identify as the IPs they provide belong to a physical location.
From bypassing geo-restrictions and IP blocking to SEO monitoring, there are various uses of residential proxies. In this article, we will be sharing the five most essential benefits of residential proxies. So, let’s get started.
Below Are Five Use Cases for Residential Proxies
SEO Monitoring: Many people use residential proxies for SEO monitoring and optimization. SEO monitoring is used to make your site rank in the search engine. This way, the visibility of your website increases, and more traffic is drawn to your page. However, the question is how residential proxies can help you with SEO monitoring.
For this, you need to understand that digital monitoring and web scraping go hand in hand. Residential proxies are the best for web scraping as they offer robust security. You can use them to scrape large amounts of data easily without getting caught. The data gathered can then be analyzed for gaining insights, learning about your competitor’s business strategies, price monitoring, popular keywords, and various other things that will, in turn, help in SEO monitoring.
Data Crawling: Another critical use of residential proxies is data crawling. With residential proxies, you can retrieve plenty of relevant data within minutes. Extracting relevant data from thousands of web pages isn’t easy when done manually. If done manually, it will take days or even weeks. Therefore, almost all companies use bots to crawl data. However, bots are easy to detect because of the security that websites have.
To crawl data using bots, you need residential proxies. Residential proxies make it difficult for websites to detect data crawlers by masking your IP address. Moreover, since the IPs used by residential proxies belong to a physical location, you get maximum security.
Alternative Data Collection: Alternative data is becoming immensely popular among e-commerce companies. It is used by online businesses to gather actionable insights, consumer sentiments, track customer behavior, know their target audience, and boost sales. However, collecting alternative data is a tedious task. It requires gathering data from different e-commerce platforms, and companies use bots for that.
It is important to use residential proxies with your bots to collect data without any restrictions. Residential proxies help in gathering data from multiple sites without the issues of geo-restriction and IP blocking. It also increases the speed at which the data is collected.
Ad Verification: Another vital function of residential proxies is ad verification. First, residential proxies help to test your ad in multiple locations by letting you bypass geo-restriction and IP blocking. Second, residential proxies help in detecting fraud ads without disclosing your true identity. They mask your real IP address and let you find irrelevant ads by remaining anonymous. In this way, you can stop your competitor from defaming your brand.
Social Media Monitoring: Many people widely use different social media platforms such as Instagram, Facebook, and LinkedIn for e-commerce. Residential proxies come in handy when you try to handle multiple social media accounts, reach out to different audiences, promote your business in different locations, run social media campaigns, gain insights, run multiple accounts, and so on. This is a pretty standard practice for Social Marketing Media Agencies, which means you should probably do it too.
Residential proxies have many essential uses. Because of the robust security, many online businesses and social media marketers have started using residential proxies. Unlike other proxies, residential proxies mask your IP address with an IP address from a physical location. As a result, you get more security compared to data center proxies. From maintaining your online privacy to let you browse the web without any restrictions, residential proxies are extremely useful. Nowadays, residential proxies are widely used for SEO monitoring, social media monitoring, data crawling, ad verification, and alternative data collection.
With many businesses turning to online platforms, SEO optimization and social media monitoring are becoming immensely important. Companies and brands frequently require extracting large amounts of data from different websites. They also need to reach out to target audiences from other locations, run social media campaigns, manage multiple accounts, etc. Residential proxies come in handy in all these cases. Moreover, extracting relevant information isn’t that easy. However, data crawling is not a hassle with residential proxies. They help brands gather significant data by skimming through the vast amount of data available online. Hence, residential proxies are extremely important, and their demand is increasing day by day.
