Types of Proxies: What You Need to Know

There are many types of proxies, and knowing which one to use can be difficult. However, this blog post will help you make sense of the different proxy types so that you can find a good fit for your needs.

What is a Proxy Server?

A proxy server is a computer that fetches resources on behalf of other computers. This can be used for security purposes, such as hiding web browser requests if you are using Tor. In this case, your IP will not show up in logs or through any public searches because it’s hidden behind the proxy server.

Proxies also eliminate bottlenecks and allow companies to distribute workloads across their servers. For example, Netflix uses these types of proxies so they can process an incoming video request from various sources at one time rather than receiving them all sequentially – giving users more streaming options without affecting workload distribution within its network infrastructure.

How does a proxy work?

Web proxies are a type of proxy server that is used to fetch resources on behalf of other computers. Web proxies work by accepting the request and returning it back to the client without actually connecting or forwarding any data. This allows for simple caching, monitoring, access control, etc., but makes them unable to support more advanced web protocol features such as SSL/TLS encryption (HTTPS) or interactive content like chatty scripts embedded in HTML pages – they can only return what was requested rather than performing additional requests themselves. A good example would be if you wanted an image hosted at another location: your computer will send a request through the proxy then download it when received.

Difference between open and a closed proxy

An open proxy doesn’t require authentication while a closed proxy does. This means an open one can be used anonymously without having any additional credentials needed, whereas you’ll need some sort of credential (username/password) in order to use it with a closed-proxy server.

Types of Proxy Servers

There are many different types of proxy servers that you can use depending on your needs. Some examples include:

  • Transparent proxies – a type of proxy server which will forward the connection between client and target server without changing anything about it, in most cases not even an addressing information or ports being used
  • Anonymous proxy – a proxy server that does not keep the user’s IP address, but will forward traffic from the client to target and back without adding anything like additional headers or tags.
  • Reverse proxies – a type of proxy server which is typically used for load balancing and caching. This type of proxy can also be used as an access control point where you can configure your firewall to only allow certain types of connections through port 443 (HTTPS) instead of allowing all connections through port 80 (or the default connection port for web browsing).
  • High anonymity proxy – a type of proxy server that is designed for use in high-security environments or where access needs to be restricted on a per-user basis. This will allow users to make connections without disclosing their identities.
  • Secure Shell proxy – a type of proxy server that works using an SSH Tunnel to create encrypted connections between the computer and remote servers.
  • Forward Proxy – a type of proxy server that is typically deployed in front of a corporate network to enable web browsing and other Internet services for users who are inside the private local area network (LAN).
  • Distorting Proxy – a type of proxy server that alters the sequence and/or timing, or the number of packets in an exchange between client and target to hide what is being exchanged.
  • SSL Proxy – a type of proxy server that provides encrypted connections between a client and a remote server.
  • DNS Proxy – a type of proxy that is designed to be used for interception purposes in order to filter or redirect traffic before it gets passed on to the destination DNS server, often because they are unable to access particular domains due to region blocking

Proxy vs Vpn

A proxy server is a computer that fetches resources on behalf of other computers. VPNs route your internet traffic through an encrypted tunnel, providing security and privacy from prying eyes such as hackers or advertisers. Unlike proxies which are limited to accessing only those servers it has been given permission to connect with, users can choose the best available connection for any given moment – such as using a free Wi-Fi hotspot when they’re out and about rather than relying only on cellular data.

Proxy or VPN, which one should you choose?

It is best to use a proxy server if you are only interested in surfing the web and want to avoid being tracked. If you would like added security, then it is recommended that you invest in a VPN service so that your data can be encrypted while it travels over public WiFi networks as well as other insecure connections.

Conclusion

Understanding how a proxy server works and the various types that are available is essential for being able to make informed decisions about which type you should use.
