ما هو الخادم الوكيل؟

A proxy server is a middleman between your device and the internet — like asking a friend to place an order so the restaurant never sees your address.

A proxy is a machine that sits between you and the web. Your request hits it first, it forwards to the destination, then relays the response back to you.

Proxies do more than hide your address: they add security, mask your IP for privacy, cache pages for speed, and enforce access control.

The flow is simple: your browser asks the proxy, the proxy fetches the page on your behalf, then hands the server's response back to you.

A forward proxy sits in front of clients and forwards their requests out to the internet. Clients are configured to use it, so the destination sees the proxy, not them.

You'll find forward proxies in corporate networks filtering outbound traffic, bypassing geo-restrictions, and adding anonymity by masking the client IP.

A transparent proxy intercepts traffic with zero client config — users don't even know it's there. Routers quietly redirect traffic through it.

Transparent proxies live at the network edge: ISPs cache content with them, public Wi-Fi enforces terms of service, and home routers filter for kids.

Proxies boost privacy because the destination sees the proxy's IP, not yours. But the proxy itself can log you — pair it with a VPN for real anonymity.

Based on what we've learned, what is the primary role of a proxy server?

You've got the core: a proxy is a middleman for your requests. Forward proxies are client-configured; transparent ones intercept invisibly. Next up: reverse proxies.
