“Understanding a proxy server and types of proxy server” is an article meant to summarize the meaning of a proxy server, and also to share in details the various types of proxy servers.
Now, what is a proxy server?
A proxy server is a server that stands as a intermediary for requests from internet users seeking resources from other servers.
This is how a proxy server works:
1)    An Internet user (you and I, technically called clients) connects to the proxy server requesting for some services that are available from a different server. On receiving the request, the proxy server does evaluation e.g. by filtering traffic using its IP address. If the request s granted, then the proxy server provides the resource by connecting to the relevant server and soliciting for the service on behalf of the clients.
Primarily, a proxy server does or offers two purposes:
a)    It keeps machine anonymously- basically for security measures
b)    It uses caching to speed up access to a resource
Types of proxy servers
Caching proxy server
Web proxy server
Content filtering proxy server
Anonymizing proxy server
Hostile proxy server
Intercepting proxy server
Suffix proxy server
…………goes the list….
Caching proxy server
A caching proxy server retrieves content saved from a previous request made by the same client, thereby accelerating service requests. A caching proxy server also helps to reduce hardware cost.
Web proxy server
A web proxy server basically focuses on World Wide Web traffic. A web proxy server typically functions as a web cache
Content Filtering Web Proxy
The basic function of a content filtering web proxy server is to provide administrative control over the web content that may be relayed through the proxy. A content filtering proxy often allows user authentication to control web access.
Anonymizing proxy server
This type of proxy server generally does web surfing anonymization. The open proxy is the most common variety of anonymizers because it is easy to track e.t.c.
Intercepting proxy server
An intercepting proxy combines a proxy server with a gateway or router. In such development, connections made by client’s browsers through the gateway are diverted to the proxy without a client-side configuration.
