How Do Proxies Work?



How Do Proxies Work?

While some specific proxies types are made possible thanks to emerging tech, in general, proxies are not a new invention. You can see proxies mentioned all over the web. Some emphasize their usefulness in terms of getting access to geo-blocked content, while others praise them as a go-to business solution.

 

Before we get into any specifics about how proxies work, their use cases and types, and how to configure the Firefox proxy setting, let’s first define what a web proxy is.

Definition of a web proxy

A web proxy is a term used to describe a remote server that acts as an intermediary between you and the rest of the world wide web. Simply put, it’s a gateway your entire outgoing and incoming traffic goes through.

 

For instance, when you type an address in your browser and hit enter, you won’t be making a direct request from the web server. Instead, your proxy server will do it for you and forward you the data packets the web server returns.

What web proxies do

Besides being a gateway, a web proxy can do a lot of different things. It all depends on how it’s configured. In general, a proxy can provide quite a wide range of functionalities. It can enhance your security and online privacy by allowing you to mask your real IP address.

 

Since proxy enables users to access the internet from a different IP, they can serve as a geo-block bypass. With a proxy, users can access otherwise geo-locked web content.

 

You can set proxies to provide their users complete control over internet usage. Users can whitelist and blacklist certain websites, online apps, and various services. Among other things, proxies can also cache online data to improve browning speeds and overall network performance in a company.

Types of web proxies

There are various types of proxies depending on what tech they are built on what functionalities they offer. Here are the most common type of proxies you should know about:

     Residential proxies – these proxies have a real residential IP address often used for web scraping operations as they appear like real human users.

     SOCKS5 proxies these proxies use the SOCKS5 protocol and are often used for bandwidth-heavy tasks.

     Private proxies these proxies are dedicated to only one user, which is why their other name is dedicated proxies. They deliver high performance and complete anonymity.

     Shared proxies unlike private, shared proxies are used by multiple users. They are more affordable but also expose users to some specific risks.

     HTTP proxies you can set up these proxies to serve as HTTP servers or clients. They have multiple uses, such as content caching and filtering.

     Rotating proxies these proxies are great for preventing being blacklisted or banned since they assign a different IP address for every connection.

How are proxies used in business

Proxies have found different use cases in business running from improving online security to streamlining web scraping operations.

Privacy and security

Businesses use proxy to enhance privacy and security for employees when browsing the internet. Setting up a proxy in a web browser is really easy. Here’s Firefox's proxy setting as an example.

 

Step 1 – Access network settings

 

To access network settings in Firefox, open the menu and click on Options.

 

Then, scroll down to “Network Settings” and click the “Settings” button.

 

Step 2: Choose a relevant firefox proxy setting

 

As you can see, the default Firefox proxy setting is “Use system proxy settings”. It tells Firefox to use the proxy configured in your system settings.

 

If you want to configure Firefox proxy settings manually, click on “Manual proxy configuration” and type in the information your proxy provider gave you.

Traffic control and bandwidth savings

Organizations often leverage proxies to minimize operations costs. Bandwidth savings are easy to achieve with proxy. An organization can identify the websites and online services their employees use on a day-to-day basis and configure the proxy to cache them.

 

Businesses use proxies to restrict access to certain websites, thus improving efficiency and productivity. Proxies also enable companies to log the entire traffic and be able to spot some discrepancies easily.

Web scraping

Finally, web scraping is another common use case of proxies in the business environment. Web scraping refers to extracting public data from websites. Many companies rely on it to research competition, discover consumer sentiment, fuel their competitive pricing strategy, or do a background check on potential employees and partners.

 

Proxies, especially rotating and residential proxies, enable businesses to run web scraping without the risk of getting interrupted or banned.

Conclusion

Proxies are a simple solution for many challenges both businesses and individuals face when online. They can help organizations take full control of the traffic, add a layer of security, facilitate online privacy, and benefit from web scraping while mitigating associated risks. Setting up a proxy in a web browser is easy. You can follow the provided Firefox proxy settings above to set up a proxy in your browser.
