Proxies act as intermediaries for any requests that are made from a client to other servers on a network. The client will connect to the proxy server and makes a request. The server evaluates the information on the other end before sending it to the user.
Proxy servers add more structure to systems that are distributed across multiple networks, and it allows for stronger encapsulation of any data that passes through them. Most of these servers are web-based, which means that they are able to facilitate communications between authorized users and different areas of the Internet. They can offer stronger security while they’re surfing the web, and they can make the client appear anonymous.
Types of Proxies
Proxies can exist on either the user’s computer, or they can be on a server somewhere on a local network or on the web. They can serve a variety of functions, so they can have several different implementations. However, there are a few main types of proxy servers:
They can be accessed by anyone, and it’s estimated that there are “hundreds of thousands” of them scattered across the web. They’re designed primarily for the purpose of concealing the identity of the user (called “anonymous open proxies”). The anonymization can occur in varying degrees, and it can be done in a variety of ways. However, many of them are designed to hide the person’s IP address while he or she is surfing the web.
Also called a “surrogate,” a reverse proxy appears to be a regular server, but the request is forwarded to other proxy servers on the network. They handle the request before it’s sent back to the user as if it came from the original server.
A reverse proxy will be set up somewhere in the vicinity of the other servers, so it will primarily be used in smaller, more localized networks. Additionally, any traffic passing through that network has to go through the proxy, and they can only process traffic going into that network. This is the opposite of a forward proxy, which can access many different areas of the web.
How Proxies Can Be Used
Proxy servers can be used in several different ways, so they can have a variety of implementations. The most common ones are web proxies, which are used mainly for anonymizing the user. However, there are other applications for these types of servers, and they all have their uses in different aspects of Internet activity.
Many schools and government organizations use proxy servers to filter content in order to provide more control over what users can access to. Usually this is put in place to make sure they comply with the “acceptable use policy.”
Most of them use crawlers to evaluate web content, which will be put into different groups. Any content that falls within a blocked group will not be seen. Some servers can also “blacklist” specific sites that they feel is inappropriate for their environment.
Ironically, proxy servers can also be used to circumvent these restrictions, and they can be used to bypass censorship or geographic restrictions as well. They are commonly used by college students in order to circumvent content filtering that has been implemented on many university campuses.
Proxy servers can also be used to improve performance on a network, which is accomplished by locally storing frequently accessed content. Many companies use them to add an extra layer of security by restricting access to encrypted data.
Proxy servers can also be used to make a website more accessible to global markets. Any request that is made by an international user is sent to a translation proxy, which will send the information back in his or her native language.
Using a Proxy Service
The most common reason why people use proxies is to create more anonymous web-browsing, so most of them are web-based. Instead of setting up a proxy server in their own homes, many people prefer to use a proxy service. The most likely reason is because they are easier to implement, which gives the user a more hassle-free experience.
Local Proxies has a number of solid proxy servers to choose from, which can help you to improve your security on the web. Most importantly, your information will always be secure, so your privacy on the Internet will never be compromised.
