A Proxy Server is related to the computer or any software system functioning on a system (computer system). This system acts like an intermediate between the final devices like any server computer where the client or user requests the service. Same like the firewall machine, proxy server also exists on a single machine or there is also the possibility that it can be on some different server, and then it forwards requests with the firewall.
Advantages of using a proxy server
The cache of the proxy can serve multiple users. If in any case more than one internet sites are requested, they are expected to be in proxy’s cache directly improving the client response time. A proxy may log to its interactions that can be beneficial for compensation.
For example, when a proxy server obtains an internet source just like the web page, it seems as a local cache of formerly pages. And if it gets that page, it directly returns back to the client without wanting to forward that to the client.
These proxies are used for legal as well as illegal prospects. In some enterprise, this server is mainly used for facilitating security, caching services and organizational control. For the personal context, these servers are used for reverse purpose i.e. for monitoring the traffic and challenging user privacy. The Proxy server like VPN is invisible and the internet requests appear to be straight with the accustom internet server. We cannot say that proxy is totally invisible, as the IP address must be certain like the configuration option in the search engine or protocol programs.
The functions performed by the proxy servers are as follows:
Caching: The proxy server and Top VPN generally stores the repeatedly requested web objects and then transfers it directly when the user requests. This saves the transmission time and reduces the latency i.e. the real time taken by the server for some objects arrival and request.
Security purpose: As all the communications of the official and corporate network travels through the proxy servers hence it can perform some of the security operations such as content filtering, URL filtering etc.
Anonymity: As the proxy server offers a common IP address over the internet, the personal IP address of the user is not exposed on the corporate network. But few proxy servers can prevail the request on numerous servers for making it troublesome for the stranger over the internet for guessing the IP address.
