Proxy servers now perform various functions to fit user needs. In general, proxy servers can change your IP address, filter unwanted content and set other restrictions on Internet access.
Most Internet users simply connect to proxy servers to access blocked websites. Some of you don’t even know you’re using the proxy servers. If you’d like to learn more about various proxy servers, you’ve come to the right place. This post shows you all you want to know about the proxy servers.
What happens when you browse the website?
When a user browses the website, he or she will generally do the following things:
- Open a browser and enter the URL. At this time, the browser secretly keeps the process in history.
- A connection request will be sent from the user’s home network, and then through the Internet provider’s backbone network, and finally to the website requested by the user. This website can see that the request is from the IP address of the user.
- Then, the website returns data to the user, and most content of the webpage will betemporarily stored in a temporary file in the user’s computer.
- If the user registers/logs in, the user’s loginin formation will be saved/updated on the server. Cookies are kept locally as a way to authenticate the user and avoid repeated logins. Of course, the phone number, email address and home address filled in during registration will also be recorded by the browser to facilitate the next login.
As you can see, there are generally three types of data stored on the user’s computer throughout the process: browsing history, temporary files and cookies, and information entered in forms. To stop this, you can use your browser’s private browsing feature.
While there are one or two types of data kept on the website. That is the IP address and registration information you entered. Proxy servers will help you hide the true IP address you have.
What are proxy servers?
A proxy server sits between you and the website you want to visit. It handles your web requests and data about the website, making your web surfing easier and more secure. It helps you to unblock websites, too.
How does a proxy server work?
When you visit a site by clicking on a link or entering the URL manually in a browser, a request is generated and forwarded to the proxy server. The proxy server then modifies and encrypts your request data (such as hiding your IP address) and sends the request to the server of the website.
The proxy server forwards the data returned by the website to you. It can serve as a firewall or web filter so you won’t see unnecessary details like irritating ads.
Common types of proxy servers
Proxy servers can be divided into three types:
1. Transparent proxy server
Transparent proxy servers collect requests from their users to block access to certain websites or content. If your request is approved, the proxy server will forward your request to the website’s server. Your IP address is invisible to the websites server because the request appears to be sent from the proxy server.
The transparent proxy server has complete administrative control over the Internet access of the local network users. It acts as a shield or firewall which allows administrators to decide whether to allow internal network users to access the websites. Transparent proxy servers are commonly used for filtering content by schools and businesses.
2. Reverse proxy server
Unlike a transparent proxy server, a reverse proxy server works alongside web servers to receive and forward requests from the clients. It’s intended to mask web server IP addresses from external users.
Reverse proxy servers make targeting internal servers difficult for hackers. Additionally, there is a load balancing feature that distributes data between internal servers to prevent server congestion caused by a large number of requests for connections. Many web service providers use this kind of proxy server.
3. Anonymous proxy server
The anonymous proxy server can not only submit Internet users’ requests but also receive website responses. It hides your IP address from the websites you visit. By connecting to an anonymous proxy server, you can change your IP address to access blocked websites.
Cons of proxy servers
Although there are many use cases on proxy servers, they can not encrypt your Internet traffic like a VPN. Your data remains vulnerable to hackers, cyber-criminals, etc. If you are using a VPN service to browse the Internet, it will route your traffic data through an encrypted tunnel. VPNs are born to make your online activity anonymous and safe.
