Detailed explanation-1: -A proxy server is an intermediary server that retrieves data from an Internet source, such as a webpage, on behalf of a user. They act as additional data security boundaries protecting users from malicious activity on the internet. Proxy servers have many different uses, depending on their configuration and type.
Detailed explanation-2: -A proxy server, also known as a “proxy” or “application-level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the internet. Proxy servers provide increased performance and security.
Detailed explanation-3: -A proxy server may reside on the user’s local computer, or at any point between the user’s computer and destination servers on the Internet. A proxy server that passes unmodified requests and responses is usually called a gateway or sometimes a tunneling proxy.
Detailed explanation-4: -Proxy servers get their name because they act like a proxy (a stand-in) and act on behalf of a Client’s computer. A client that connects to the proxy server will ask for some service, such as a file, connection, web page, or other resource, that is available on a different server.
Detailed explanation-5: -A reverse proxy is a server that sits in front of one or more web servers, intercepting requests from clients. This is different from a forward proxy, where the proxy sits in front of the clients.
