The Functions of the Proxy Server
A server is a combination of one or more hardware and software made 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 managing a server operating system.
A proxy server could therefore certainly be a firewall mechanism that substitutes the IP address of the protected host network with 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 on behalf of the consumer.
In essence, it is a computer that acts as an interface or intermediary to connect two or more computers which have different protocols and therefore are placed at various remote locations on the internet.
Whenever a user (computer) attempts to connect with another user to consider any resources such as files, web pages, connections, etc available on their database, it's the proxy server that evaluates if such connection is permitted based on the existing settings on the remote computer. When the proxy server authenticates these the weather is met, after that it makes the request with respect to the consumer and establishes the connection.
The proxy server can either modify either the request or response of the user or client or, react to a request without contacting the server. It does this by using cached similar responses stored on the remote server the resources are being requested from.
Another functions include:
1. It reduces the time required to access resources from servers by serving cached responses for similar request to clients. 2. It serves a log to provide info on internet usage for auditing or evaluation purposes. 3. It could be accustomed 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 could be accustomed to block use of unwanted or unauthorised sites 7. It serves as a scan to filter malware before delivering requested resources 8. It works as a scan to block certain outgoing data. This is for protected files
Since it is an intermediary that acts with respect to two or more users or clients, a proxy server can be placed anywhere in-between the users or at destination servers on the internet for this for everyone its functions.
