What Are Proxy Servers, and How Do They Work?

Proxy Servers

A proxy serve­r functions as an intermediary connecting your device­ and the internet. Whe­n using a proxy server, it initially receives your requests for websites and online resource­s. Afterward, it transmits these­ requests to the intended website or se­rver. Finally, it reroutes the re­sulting response to the proxy se­rver, which then delive­rs it to you.

To achieve a bette­r understanding of proxy servers, including the­ir safety measures and the­ various types available, delve­ into this informative article. Explore further to expand your knowledge on these compelling subje­cts.

How Does a Proxy Work Effectively?

A proxy serve­r acts as a go-between for your de­vice and inte­rnet. In the typical case, whe­n you directly connect to the inte­rnet, your data travels now from your de­vice to the Web.

With a proxy, the process changes. When connected, your data takes a different route. Your device connects to the proxy server and sends your request to the desired website. It hides your IP address, and the website sees the proxy server’s IP instead.

Various types of proxies serve different purposes. For instance, a web proxy works with your web browser. You can also set up a web proxy on your router to direct all internet traffic through the proxy server. This article will analyze these different proxies and their abilities.

While proxies offer some security, they might not provide complete online anonymity or data protection. Therefore, using a VPN is advisable to remain anonymous and secure online. Several VPN service providers are available, with options like ExtremeVPN, ExpressVPN, and NordVPN delivering top-notch service.

Different Kinds of Proxies

Differe­nt types of proxies exist, cate­gorized based on various classification standards. A prime­ example is grouping them according to the­ir capability to accommodate users. Public proxies are­ capable of handling multiple interne­t users, while private proxie­s serve individual or small group needs.

Moreover, outsiders often face difficulties verifying specific use­r data using a public proxy. The reason be­hind this challenge lies in the­ fact that multiple users share the­ same IP address associated with said public proxy.

Proxies can be­ categorized based on the­ir specific functions. Within this category, there­ are different types of proxies available­. Some examples of the­se different proxy type­s include: 

  • Filtering proxies
  • Reverse proxies
  • CGI proxies
  • Caching web proxies

Another way to define its effectiveness is to assess the privacy level a proxy server offers. Categorization contains various types of proxies.

  • Anonymous proxies
  • High anonymity proxies
  • Transparent proxies

1. Filtering Proxies

Certain proxy servers filter website content, allowing online censorship similar to the practices followed in China and Russia. They restrict access to particular content, thereby limiting internet freedom. Further, some proxies customize web pages for various devices, ensuring a safer browsing experience and protecting against harmful content.

2. Reverse Proxies

Correct to its name, a reverse proxy works differently than a regular proxy server. While standard proxies protect users’ data, reverse proxies protect web servers from harmful attacks. They assist websites in managing access to particular web pages. For example, a bank might use a reverse proxy to secure clients’ accounts, maintaining high-security standards.

Furthermore, reverse proxies store static pages, preventing server pressure and ensuring efficient website operation.

3. CGI Proxies

A CGI proxy server works like a website, providing fast access to specific web pages. It permits users to reach websites and platforms that businesses, schools, or government entities commonly restrict.

Furthermore, it delivers a level of anonymity by hiding your IP address.

4. Caching Web Proxies

Caching web proxies are popular for faster and more secure browsing. These proxies save copies of visited websites, leading to quicker page loading. When you browse through a caching web proxy, it first checks its stored files (cache). If it finds the website, it retrieves the data without going online.

If the proxy doesn’t store the page, it brings the information online and saves a copy for future use. The cache isn’t permanent and is cleared based on data lifespan, request frequency, and size. Algorithms such as Least Frequently Used (LFU) and Least Recently Used (LRU) manage and clear the cache.

5. Anonymous Proxies

An anonymous proxy reveals it’s a proxy server but hides your actual IP address. It offers some protection against online threats. However, it can’t unblock Netflix because Netflix can detect proxy connections and limit your access to their content.

6. High Anonymity Proxies

You can categorize proxy servers based on the anonymity they provide. It offers the highest level of anonymity. Also, it makes it difficult for others to know you’re using a proxy. It hides your IP address and stays completely hidden from websites. Unlike regular anonymous proxies, it’s undetectable. However, while it’s very private, it doesn’t provide the same security as a VPN.

7. Transparent Proxies

A transparent proxy doesn’t conceal users’ IP addresses, offering no anonymity. A proxy server exposes users’ IP addresses to websites and third parties. Typically, these proxies work as caching proxies.

Pros and Cons 

Here’s a summary of the benefits and drawbacks of using a proxy server:


  • Bypasses other proxy servers or geo-blocks
  • Defends potentially dangerous codes
  • Allows users to block typical content
  • Enhances internet speed and connection
  • Hides users’ IP address


  • No whole anonymity
  • No encryption benefit
  • It may not open all blocked pages
  • Chance of IP address leak

What are the Settings for a Network Proxy?

You can configure each app on your device to use a proxy separately if it supports proxy servers. You can usually find this setting in the ‘network settings’ section.

Mozilla Firefox has integrated proxy server support, unlike other browsers. Regular proxies can also work with most web browsers and applications needing an internet connection.

Only a few devices support a global HTTP proxy, allowing specific traffic to bypass the proxy’s IP. For complete anonymity, consider other alternatives.

Your proxy settings might be in different places depending on your operating system. For example, you’ll likely find proxy settings alongside other network settings in system preferences and Wi-Fi settings on Windows and macOS. Further, many web browsers have their proxy settings.

Before setting up a proxy server, you’ll need the IP address, hostname, port, and type of connection.

The Best Way to Check Your Proxy Settings

After configuring it on your system, you can verify that you did it perfectly by checking your public IP address. To do this, enter “what is my IP address” on Google or whichever search engine, and you will know how your data travels until it arrives on the internet through the respective channel.

However, if you desire maximum privacy against third-party surveillance, connect to a SOCKS proxy. Moreover, attach the entire device to the proxy server, including any running program you launch. Nevertheless, it’s important to note that your web browser’s connection to the proxy doesn’t imply the attachment of other applications to your device.

VPN or Proxy

A proxy server needs to deliver complete protection and anonymity. For complete protection, it’s better to use a VPN. A VPN reroutes and secures data traffic through encryption and features like a kill switch to prevent leaks.

Moreover, VPN connections are usually faster than proxies, making them excellent for streaming and large downloads. Combining a VPN with a robust antivirus program ensures optimal security.

Leading VPNs often have a no-log policy, prioritizing user privacy. However, choosing a reputable provider is essential, as some have previously breached user trust. Consider reliable options like ExtremeVPN, ExpressVPN, and NordVPN for premium services.

How to Unblock Streaming Websites Using Proxies

Accessing a website through a proxy server works as a go-between, fetching resources on your behalf while hiding your IP address. It shields your location and device information from direct exposure to the site. Streaming platforms desire to identify and block access from specific IP addresses and regions involved in unauthorized activities linked to copyrighted content.

An anonymous proxy server allows you to bypass geo-restrictions and protect your identity on online streaming sites. These platforms aim to prevent piracy. Proxies offer encrypted tunnels and new IP configurations to access restricted content. However, they can extend legal and ethical concerns regarding copyright laws.


Proxy servers reroute your internet traffic through an external server. They speed up connections, bypass location restrictions, and provide some online privacy. However, their benefits are limited. For comprehensive online security, privacy, and complete anonymity, it’s best to choose a VPN instead.


What is a proxy server?

A proxy server acts as a bridge between the user and the internet. It directs your data traffic to an external server, fully concealing your IP address and partially hiding your location and identity. It provides some level of anonymity and unlocks geographically restricted content.

What are the disadvantages of proxy?

Proxy servers have several drawbacks. Some of them include:
1. No encryption services
2. Your IP address can track your location.
3. You will not be able to browse all blocked pages.
4. Partial security and anonymity

Do a proxy and a VPN differ?

Yes, there is a big difference between a VPN and a proxy. A VPN also offers better encryption and greater anonymity than the proxy server and, thus, rerouting services.

Why is it beneficial to install a proxy server?

A proxy server also provides several advantages. Some of them include:
1. Conceals IP addresses
2. Offers protection against malicious codes
3. Can increase connection speed
4. Can block potentially harmful websites
