Types of Proxy Servers and How They Work

Proxy servers are essentially computers that are combined with firewalls and are used by other computers to gain access to web pages. The proxy server provides resources by either connecting to the particular server or by serving it through cache. It is possible that the proxy server changes the request of the client or the response from the server for different purposes. There are different types of proxy servers and here is some information about how you can use them.

Anonymous proxy server

An anonymous proxy is basically a tool used for making one’s activity on the internet untraceable. The proxy server acts like a shield between the internet and the client system. The server provides the client access to the internet and hides the information that can be used for identifying the client’s computer.

There are many reasons why someone would opt to use a proxy server.

  • The most common one is that it helps minimize the risk. People who are wary of identity theft or those who do not want their search history to be tracked make use of such proxies.
  • Increasing the speed of internet connection is one of the other common reasons, as the proxy will help in accessing the site a lot faster, especially if it is stored in cache.
  • Another reason for using proxies is to overcome local blackouts and watch your favorite sporting events online, without any hindrances.
  • People today want objective information, but targeted online marketing makes it very difficult. For instance, CNN provides different news stories to people based on their geographic location. YouTube recommends videos based on location and past viewing history. To by pass such targeting people use proxies.

Distorting proxy

As the name suggests, a distorting proxy modifies or hides your IP address which stops target servers form obtaining your IP address. Again, such proxy server prevents hackers from gaining access to your search history and other information. Even though such proxies help in maintaining privacy, others can see whether you are using a proxy server or not.

Transparent proxy

Transparent proxy is quite different from both the proxy servers mentioned above because it does not hide the client information. The servers are capable of caching websites but are unable to provide any anonymity. Such proxies are very common in business organizations to stop acceptable use policy. Because there is no browser configuration required, it helps in reducing the burden on the administration.

In certain countries, internet service providers (ISPs) use transparent proxies for saving upstream bandwidth by caching sites. Such practices are usually adopted in countries,, especially island nations, where bandwidth is limited.

Proxy servers that provide huge anonymity

These servers provide the anonymity in a manner similar to anonymous proxy servers as they do not provide the correct IP address through headers. A high anonymity proxy server includes REMOTE_ADDR header along with the client IP address, which gives the impression that the client and proxy server are the same. So, no one gets to know about your IP address and your browsing information is also safe.

Reverse proxy

You can technically call Reverse proxy a proxy server, however there are no local policies enforced. Such proxies are mostly used for passing requests to the web through a firewall, which is isolated using private networks. Reverse proxy servers are used mainly when you do not want the client system to gain unmonitored access to content residing on isolated servers.

Essentially, proxies are used for keeping your internet browsing anonymous, and they can be used in a number of ways. So, you should choose your proxy server depending upon what your needs are.
