Understand Proxy Server

Proxy server, understanding advantages and disadvantages, - Proxy server is a computer server that acts as another computer for receiving or requesting content from an internet or intranet network. Proxy servers act as gateways for every client computer. The web server that receives requests from the web proxy translates them and looks like the request comes directly from the client computer.

Proxy servers can also be used to secure private networks that are connected to a public network. Proxy servers have more functions than routers that contain packet filters, because the proxy server operates at a level with more extensive control over network access.

Benefits of Proxy Server

The advantages of proxy servers in a TCP / IP network are:
Network security is better maintained because there is a proxy as a barrier between local networks and external networks (internet)
Reopening the sites that were previously opened is faster because access to the external network (internet) is not necessary, but it is in the proxy cache folder.
There are filtering facilities, both user filtering, content and access time.

Lack of proxy servers

The lack of a proxy server in a TCP / IP network is:
Access to sites that have never been opened before will be slower because the client must first request the proxy, after which the proxy will request the client from the internet provider.
If the proxy server is late in updating the cache, the client receives content that was not updated when requesting the content.
