Proxy Server

A proxy server is an intermediary server that sits between a client (e.g., a user's device) and other servers, forwarding requests and responses. It can provide functions such as caching, filtering, logging, and anonymizing traffic, often used to enhance security, performance, or access control in network communications.

Also known as: Proxy, Forward Proxy, Reverse Proxy, HTTP Proxy, SOCKS Proxy

Why learn Proxy Server?

Developers should learn about proxy servers when building or managing networked applications that require traffic control, such as web scraping, API rate limiting, or load balancing. They are essential for implementing security measures like firewalls, monitoring network activity, and bypassing geo-restrictions in development and testing environments.
