A proxy server provides a local source of data or services to one or more clients and may also provide caching and forwarding capabilities. The Internet is littered with examples of proxy servers, including websites like YouTube and Wikipedia.The term "proxy" comes from the French verb "faire passer"—to cause something to go by, or to provide a means of passing through. In the networking world, proxy servers are designed specifically for security reasons.
Types of Proxy Protocols:
A proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity. The request passes through the proxy server to the requested server, which provides service for it. If the request is valid, then the response from that server is returned to the original client. If a request appears invalid (for example, if it doesn't match any resources available from a different server or if a required resource is unavailable), then an error message or some other kind of appropriate response signal is returned. The proxy server may be a client itself, or it may be a server with the ability to serve clients. For example, it could receive requests from another proxy or directly from clients and return responses to them.
There are two types of Proxy Protocols: http proxy protocol and https proxy protocol. Such protocols of proxies are available at https://youproxy.io/en/ for example.
How to Choose The Right Protocol for your Network Needs?
HTTP stands for Hypertext Transfer Protocol. HTTP is the most popular protocol used on the internet to transfer web pages. HTTPS is a secure version of HTTP, which means it encrypts data as it travels over the network.
FTP stands for File Transfer Protocol. FTP is a protocol that allows you to transfer files from one computer to another computer over the network.
