Proxy Server List

Types of Proxy Servers

There are many different types of proxy servers, and all of them have their own place in the proxy world.

Some of these types may overlap, but it is important for you to understand all of the different types of proxies available so that you know exactly what you are dealing with when you use a proxy server.

  • First off, there are caching proxy servers. These are servers that, basically, retrieve saved content previously searched by clients in order to speed up content retrieval. These are very popular for use in large businesses, and were the very first type of proxy servers. 
  • Second, there are Web proxies. Web proxies focus mainly on Internet web traffic, and also serve as web caches.

These programs provide for filtering by use of a blacklist that denies access to certain URLs. This type of proxy is used in libraries, educational establishments, and for corporate computer systems where content filtering is needed.

Filtering may also be achieved by utilizing methods such as URL regex filtering, content keyword filtering, or even MIME filtering. It may also produce logs to show what URLs were accessed. This is especially popular for use in schools and other private or public organizations. Web proxies can also anonymize web surfing by using open proxies to make themselves less visible to political dissidents or computer criminals.

 

 

  • Hostile proxy servers are servers that are installed to eavesdrop on web usage and data flow. These types of servers record things like passwords, submitted forms, and other data which can be reviewed by the proxy operator. These types of proxies are dangerous to use, and should be avoided.
  • Intercepting proxy servers actually combine a gateway or router with a proxy server. These types of proxy servers basically serve two purposes. First, they help to avoid violations of the acceptable use policy, and second, they help to ease the administrative burden by not needing a client browser configuration. They are commonly used in many countries to save bandwidth, and to improve the time it takes to respond to customers.
  • Some proxies are called transparent proxies, and they are supposed to be proxies that do not modify the response or the request of the data other than what is necessary for authentication. However, these proxy servers have been known to have security flaws, so it is important to use a trusted proxy if you go this route.

  • There are some proxies called forced proxies, and they are called forced proxies because they require you to use the proxy to gain the connection, even if you do not want to use it. There are many different types of forced proxies, and they are actually fairly common. 
  • A reverse proxy server is a type of proxy that is installed in front of one or more different web servers. Basically, all of the traffic coming in from the internet to one of these servers will go through the proxy, hence the term “reverse proxy”.
  • A tunneling proxy server is a type of proxy server that you can use to defeat some type of blocking policy. These servers will basically tunnel you to a site so that you can view pages you would otherwise be blocked from. 

There are many different kinds of proxy servers, and available proxy server lists on the internet; some you may use every day and some you may never use, but they still exist, and you may even utilize more proxy networks than you realize!
