Reverse proxy server is an effective encryption tool that helps to distribute and balance the load and delivery of cached content. Reverse encryption has its own features, advantages and disadvantages that are worth knowing about. Here is a brief but concise guide.
How Reverse proxy works
After studying the principles of reverse proxy operation, you will realize that the system is simple but effective. We have highlighted 4 main “whales”.
A proxy server changes the real IP address to the IP of the service. Changing DNS A-records helps to hide the user’s location and bypass content blocking.
The operating system requests an address that matches the DNS resolution.
DNS provides the location address of the service by responding to a query.
When opening an HTTP session, the browser sends a request to the service. The latter in turn passes the request to the target web server, re-establishing a connection with it.
Uses and limitations of reverse proxies when connecting
You can use reverse proxy for various purposes. The multifunctional system effectively enhances security, provides load balancing, and serves different types of content. Although resident proxies are considered a more valuable resource, reverse proxy systems have a lot to offer.
Business Applications
The system improves SEO customization, helps ensure data security, load balances, and more. Reverse connection carries lower costs, which can be an optimal solution for small businesses. Separately, it is worth noting the creation of a secure environment. It is difficult to hack a reverse proxy, which makes the protection of company data more reliable. The system protects against a wide variety of actions of intruders, including malicious file infiltration, information theft, etc.
Integration with existing infrastructure
Reverse Proxy can be integrated into an existing system. This greatly simplifies the process of creating a secure environment. You can select mobile proxies that match the amount of infrastructure, the load on it, etc. You don’t need to re-create the site, develop a file storage system. You just integrate the reverse proxy into your business or daily use and get the updated benefits.
Is it possible to detect the use of reverse proxies?
Reverse proxies are, in essence, a classic proxy system with an additional external server. The additional layer of user interaction with the network, provides the role of a kind of filter that protects the main server with information from attackers. As a rule, it is difficult to identify such a server, for this you need to calculate both components. Of course, it is possible to do this if you set a goal and know where to “hit”.
Advantages of reverse proxy servers
A modern reverse proxy is a good means to protect and supplement business processes in the online segment. It has a number of advantages that make the system very popular.
Caching preserves unchanged site data.
By filtering and checking requests, server security is improved. Malicious codes are timely blocked, DOS attacks are prevented, and any suspicious traffic is frozen.
Facilitated certificate management, thanks to SSL encryption decryption.
Complete anonymity online thanks to real address spoofing.
Extensive customization options to improve the efficiency of interaction with a particular customer.
Creation of a single logbook, with information recorded in it.
It is also worth highlighting several significant advantages that make the use of proxies justified and even necessary. These advantages apply not only to reverse connection, but also to classic proxies. Some companies prefer to connect super proxy services, which have enhanced characteristics.
Increased security
This is probably the most important indicator – security. Both ordinary users and business owners are trying to achieve it. Reverse proxies help to provide a high degree of protection, encrypt and decrypt requests (both incoming and outgoing), reduce server load, and ensure anonymity.
Fast delivery of encrypted content
Continuous caching of requested data points improves the user experience by delivering content quickly. This allows you to provide customers with access to information, and respond to requests at the same time. Fast content delivery makes network utilization comfortable and secure.
Distributed load balancing
The proxy evenly distributes client requests between servers, creating a balance. This approach prevents congestion and makes resource utilization efficient. Distributed balancing balances any load by spreading it out.
Simplified administration
Even a novice can handle reverse proxy administration. The simple and clear system seems to be designed for people with no experience. This applies not only to the encryption part of the admin area, but also to the functionality for SEO promotion. Often users need help connecting or using the system. For this purpose, various proxies have an online support chat room, where specialists are ready to come to the rescue, and solve any issue privately. Make sure that the proxy you choose has such a service.
Flexibility and scalability
The proxy has a system to simplify scalability. You don’t have to configure each server individually. All requests are handled at a single point. In the settings, you can give the proxy the task of redirecting requests to additional capacity that is currently available.
Setting up and managing Reverse proxy
After learning what a reverse proxy is, you probably have a question about using the server on your own. You can configure and manage the proxy yourself, but you need to know a few nuances. You should start with studying the commands. We will cite a few of them. You can learn about other commands separately.
- PASS/OC – create a rule using UPL.
- enabled – working with the enabled rule (yes/true or no/false).
- name – create a name for the reverse proxy.
- desc – description of rules.
- is_https – HTTPS support.
- profile – server to send the request to the user.
- ssl_profile – SSL profile.
- certificate – HTTPS support certificate.
- src.ip – using the command src.ip = lib.network() you can create a list of addresses by specifying the name of the list. The command can also be used to create a list of domains.
- rewrite_path – designed to reverse an incoming request by substituting the domain and/or path.
Reverse proxy is a simple and clear way to improve the system of work in the online space, create a safe environment, improve business processes. You can work with proxies on your own by finding the right one for you, installing and configuring it. If you don’t have time and desire for this, it is worth ordering a proxy checker.
