The Functions of a Proxy Server
A server is really a mixture of one or several software and hardware designed to provide networking plan to clients. Individually, it could also make reference to any software or dedicated hardware used to provide such service or any system that's running a server operating-system.
A proxy server could therefore be described as a firewall mechanism that substitutes the IP address of a protected host network having a temporary address for all data traffic passing through it. It makes decisions to authenticate the user or client IP address' permission to gain access to the network and establishes link with any remote computer with respect to the consumer.
In essence, it is a computer that acts as an interface or intermediary for connecting two or more computers that have different protocols and are placed at various remote locations on the internet.
When a user (computer) tries to connect to another user to consider any resources for example files, webpages, connections, etc on their database, it's the proxy server that evaluates if such connection is permitted based on the existing settings on the remote computer. Once the proxy server authenticates that these conditions are met, after that it helps make the request with respect to the user and establishes the bond.
The proxy server can either modify either the request or response of the user or client or, respond to a request without contacting the server. It will this by using cached similar responses stored around the remote server the resources are now being requested from.
The other functions include:
1. It reduces time needed to access resources from servers by serving cached responses for similar request to clients. 2. It serves a log to supply info on internet usage for auditing or evaluation purposes. 3. It may be used to over-ride security or parental control 4. It enables use of regionally restricted resources 5. It hides its clients for anonymous browsing and security 6. It may be used to block access to unwanted or unauthorised sites 7. It serves as a scan to filter malware before delivering requested resources 8. It works as a scan to bar certain outgoing data. To protected files
As it is an intermediary that acts on behalf of several users or clients, a proxy server can be placed anywhere in-between you or at destination servers on the internet for it for everyone its functions.
