This article will explain in detail what the types of proxy servers are, and the editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

While all proxy servers provide users with alternate addresses to use Internet, there are several different types of proxy servers-- each with its own functionality.

1. Freight forwarder

The forwarding agent is located at the front end of the client and is used to send data to user groups in the internal network. When a request is sent, the proxy server checks it to determine whether it should continue to connect.

Forwarding agents are best suited for internal networks that require a single entry point. It provides IP address security for users on the network and allows direct management control. However, forwarding agents may limit an organization's ability to meet the needs of a single end user.

two。 Transparent proxy

Transparent agents can provide users with the same experience as home computers. Thus, it is "transparent". They can also "force" users, which means they contact users without their knowledge.

Transparent proxies are ideal for companies that want to use agents without making employees aware that they are using them. Its advantage is that it provides a seamless user experience. On the other hand, transparent proxies are more vulnerable to certain security threats, such as SYN-flood denial of service attacks.

Transparent proxies are best suited for users who want to be completely anonymous when accessing Internet. Although transparent proxies provide some of the best identity protection, they are not without shortcomings. Many people think that using transparent proxies is despicable, so users sometimes face resistance or discrimination.

3. Anonymous agent

The focus of anonymous agents is to make Internet activity untraceable. It works by accessing the Internet on behalf of users while hiding their identity and computer information.

4. Highly anonymous proxy

Highly anonymous agents are anonymous agents that are further anonymous. It works by deleting your information before the agent tries to connect to the target site.

This server is best suited for users who absolutely need anonymity, such as employees who do not want to trace their activities back to their organization. The disadvantage is that some of them, especially free, are baits designed to trick users into obtaining their personal information or data.

5. A twisted agent

The twist agent positions itself as a proxy for the site, but hides its identity. It does this by changing its IP address to an incorrect IP address.

For those who want to hide their location when surfing the Internet, distortion proxy is a good choice. This type of agent can make you look as if you are browsing from a specific country and give your advantage not only to hide your identity, but also to hide the identity of the agent. This means that even if you are associated with an agent, your identity is still secure. However, some sites automatically block distortion agents, which may prevent end users from accessing the sites they need.

6. Data center agent

Data center agents are not part of ISP, but are provided by another company through the data center. There is a proxy server in the physical data center through which user requests are routed.

For those who need fast response times and inexpensive solutions, data center agents are a good choice. Therefore, for those who need to quickly collect personal or organizational intelligence, they are a good choice. Their advantage is that they allow users to collect data quickly and cheaply. On the other hand, they do not provide the highest level of anonymity, which may put the user's information or identity at risk.

7. Residential agent

The residential agent provides you with an IP address that belongs to a specific physical device. All requests are then sent through the device.

Residential agents are ideal for users who need to verify site ads so that you can block suspicious or unwanted ads from competitors or bad guys. Residential agents are more trustworthy than other agents. However, they are usually expensive to use, so users should carefully analyze whether they are worth the extra investment.

8. Public agency

Anyone can access the public agent free of charge. It works by giving users access to their IP addresses and hiding their identities when they visit the site.

Public agents are best suited for users who focus on cost rather than security and speed. Although they are free and easy to access, they tend to be slow because they are plagued by free users. When you use a public proxy, the risk that your information will be accessed by others on the Internet also increases.

9. Sharing agent

Multiple users use a shared agent at the same time. They allow you to access IP addresses that may be shared by others, and then you can surf the web and look like you're browsing the location of your choice.

For those who don't have a lot of money and don't need a quick connection, a shared agent is a reliable choice. The main advantage of a shared agent is its low cost. Because they are shared by others, you may be blamed for other people's wrong decisions, which may result in you being banned from visiting a website.

10. SSL Agent

The secure Sockets layer (SSL) proxy provides decryption between the client and the server. Because the data is two-way encrypted, the agent hides its existence from both the client and the server.

These agents are best suited for organizations that need enhanced protection against threats revealed and blocked by the SSL protocol. Because Google prefers to use SSL servers, SSL agents can help its search engines rank with websites. The disadvantage is that encrypted content cannot be cached on the SSL proxy, so you may encounter a low performance situation when you visit the site multiple times.

11. Rotated proxy

The rotation agent assigns a different IP address to each user connected to it. When users connect, they get a unique address of the device they were previously connected to.

The rotation agent is very suitable for users who need to do a lot of continuous web fetching. They allow you to return to the same site anonymously over and over again. However, care must be taken when selecting the rotation agent service. Some of them contain public or shared agents that may expose your data.

twelve。 Reverse proxy

Unlike the forwarding proxy in front of the client, the reverse proxy is located in front of the Web server and forwards requests from the browser to the Web server. It works by intercepting requests from users at the network edge of the Web server. It then sends the request to the source server and receives a reply from the source server.

Reverse proxy is a powerful choice for popular websites that need to balance the load of many incoming requests. They can help organizations reduce the bandwidth load because they are just another Web server that manages incoming requests. The disadvantage is that if attackers can infiltrate reverse proxies, they expose the HTTP server architecture. This means that if network administrators use reverse proxies, they may have to strengthen or redeploy firewalls.
