What is a Proxy Server and How Does it Work?

What is a proxy server and how does it work?

A proxy server behaves as a shield between you and the Internet. It s a middleman, separating you from the sites you visit. Proxy servers offer various levels of security, functionality, and privacy based upon your use case, requirements, or business policy. They are often used in conjunction with URL filters and other filtering tools.

How does a proxy server work?

It starts by establishing an IP address and then connecting to the Internet through that IP address. Each time the user makes a web request, the requests are sent to the web server and are handled by it.

Once the data is received from the web server, the web application programs and user agents processes the information. Some of the common types of information passing through a proxy server include scripts, database queries, image data, and application data.

Why use proxy servers?

The most common reason for using a proxy server is to hide one's identity from Internet surveillance and tampering. Many companies and organizations routinely monitor Internet traffic to ensure that employees are not wasting bandwidth or accessing resources in a way that is inappropriate.

A proxy server prevents companies from being able to tell whether or not their employees are actually using Internet resources in a way that is legal or not.

How is a proxy server used in a web environment?

With web traffic, the IP address of the client is needed. By instructing the client computer to route the web request through a proxy server, the server effectively "routes" the request to the right destination. In turn, the IP address of the client is not recorded by the web server, but instead becomes the IP address of the proxy server.

This allows for data and scripts to be passed along between the client and server without any knowledge or indication of where the data came from or who originated it. Because of this feature, proxy servers are often used by Internet journalists and other news outlets to make sure that sensitive data is not inappropriately passed to sources that may be attacking the media.

Can a free proxy server provide better protection than using a paid service?

While a paid service will usually cover your IP address when transmitting web requests, a free proxy server will not. If you plan to use a free proxy server, you should exercise caution. The information you may be transmitting could contain spyware and/or malware that could expose your computer to further attack.

How do I tell if my computer is being protected by a proxy server?

A proxy server will either encrypt or block all web requests to a computer. Encryption is usually done using SSL, which is short for Secure Socket Layer. SSL creates a "secured tunnel" that encrypts data packets between the client and server.

Why is it necessary to hide my IP address while using a proxy server?

As mentioned before, most free proxy servers will only encrypt the data transmitted to the web server. This means that anyone observing your web browsing can trace your internet protocol address. A high anonymity proxy server will encrypt the information the web server receives, so that your real IP address is hidden and can only be discovered by the server itself. However, not all anonymous proxy servers can offer this level of protection. You can visit our technicalactiongroup.ca/what-tag-can-do for more details.

So, now you have a basic understanding of what proxy servers are and how they work. If you want to get the most security and performance from your online activities, you need to use a top quality anonymous proxy server. There are many free proxy servers available, but they often don't offer the level of security and performance you need.

You can choose to pay for a premium anonymous proxy server service, but these services typically charge a monthly fee. The benefits of paying for anonymous web server services far outweigh the cost.
