You might have heard a lot about the proxy servers. But do you really know what they are? In this post, we are going to explain what proxy servers are, and how they assist you when you’re connected to the internet. Let’s dive in!
In the simplest terms, a ‘proxy server’ serves as a gate between you, as an end-user, and the internet. It provides you the security, functionality, and privacy that you need to perform your tasks online.
The cache of a proxy server helps in speeding up your browsing speed. Internets sites that are accessed by the users are saved in the cache of proxy servers. If a user wants to access the site again, the proxy server would look for it in its local cache and returns the page to the user without requesting the internet, thus increasing the response time.
Types of Proxy Servers:
This is a brief explanation of a proxy server and how it works. Now, here are its types:
1- Open Proxy Server:
An ‘open proxy server’ can be accessed by anyone who uses the internet, however, this proxy type is preferred by those who want to conceal their user’s identity. The IP addresses are masked from the servers that request from the proxy server, resulting in increased security. The open proxy permits the users that belong only to a defined group.
The open proxy server has two subtypes, namely anonymous proxy and transparent proxy.
Anonymous Proxy Server – This type of server is always open and accessible to all the users and helpful, while still masking the IP address.
Transparent Proxy Server – The prime advantage of having this kind of server is that websites that you have accessed can be cached, thus increasing the response time.
2- Reverse Proxy Server
Another type of proxy server is called ‘reverse proxy’. This kind of proxy usually reside in the same network as the other components of a site and make sure that the information passes to and from the right modules and users. Most of the time all information sent to the modules is first passed through the site’s reverse proxy.
Here are some of the benefits of using the reverse proxy:
- It boosts the performance of your web by caching the most in-demand content. Proxy caching normally reduces the data traffic, thus promoting the free flow of client and server interaction.
- It can be a distributor of requests to a certain group of servers that would prevent data traffic. Requests first go through the reverse proxy, and then the proxy directs the request to a suitable server. This activity increases the data flow, therefore prohibiting the server overload and data traffic.
- When the requests land on the reverse proxy, they are masked before they’re branched out to the subsequent servers. This is helpful to protect the user’s identity, and also prevents cyber attacks.
