Types of Proxy Servers.
                Not all proxy servers work in the same way. It is important to understand exactly what functionality yo are getting from the proxy server, and ensure that the proxy server meets your use case.

Transparent Proxy.
                A transparent proxy tells websites that it is a proxy server and it will still pass along your IP address, identifying you to the web server. Businesses, public libraries, and schools often use transparent proxies for content filtering. They’re easy to set up both client and server side.

Anonymous Proxy.
               An anonymous proxy will identify itself as a proxy, but it won’t pass your IP address to the website. This helps prevent identity theft and keep your browsing habits private. They can also prevent a website from serving you targeted marketing content based on your location. For example, if CNN.com knows you live in Raleigh, NC, they will show you news stories they feel are relevant to Raleigh, NC.
Browsing anonymously will prevent a website from using some ad targeting techniques, but is not a 100% guarantee.

Distorting proxy.
              A distorting proxy server passes along a false IP address for you while identifying itself as a proxy. This serves similar purposes as the anonymous proxy, but by passing a false IP address, you can appear to be from a different location to get around content restrictions.

High Anonymity proxy.
             High Anonymity proxy servers periodically change the IP address they present to the web server, making it very difficult to keep track of what traffic belongs to who. High anonymity proxies, like the TOR Network, is the most private and secure way to read the internet.

HTTP Proxy Servers.
             These proxy servers can interpret network traffic, so they are used to cache web pages and files, making it easier and faster for users to access them. HTTP proxies can affect multiple connections at the same time without their speeds taking a serious hit

Purpose of Proxy Server.
              Proxy servers are used for both legal and illegal purposes.
In the enterprise, a proxy server is used to facilitate security, administrative control or caching services, among other purposes. In a personal computing context, proxy servers are used to enable user privacy and anonymous surfing.
