The Internal Structure and Functionality
Caching and Performance Optimization: Proxy servers can cache responses, reducing the load on the remote server and improving overall application performance.
Load Balancing and Geographic Redundancy: Proxy servers can distribute incoming requests across multiple remote servers, ensuring load balancing and offering redundancy in case of server failures.
Latency: Introducing a proxy server can add extra latency to requests, depending on the proximity and performance of the proxy server.
Proxy Server Reliability: The availability and reliability of the proxy server are critical factors. If the proxy server experiences downtime or other issues, it can affect the client-side application’s functionality.
Security Risks: While proxy servers can enhance security, they can also become a single point of failure or a potential target for malicious attacks.

When a client-side application makes a request, the Proxy object intercepts it and relays it to the specified proxy server. The proxy server processes the request, performs additional security checks if needed, and forwards it to the actual remote server. The response is then sent back to the client-side application through the Proxy object.
