الوكيل الأمامي مقابل الوكيل العكسي: اختيار الأداة المناسبة

Proxies all sit in the middle of traffic, but face opposite ways: a forward proxy represents the client; a reverse proxy represents the server.

A forward proxy fronts clients and fetches the internet for them. The destination server sees the proxy's IP, never the client's.

Reach for a forward proxy to filter and log corporate traffic, cache shared content, hide client IPs, or bypass geo and network blocks.

A reverse proxy fronts servers. Clients think they're talking to one machine, but it forwards to backends they never see.

Reverse proxies power most web infrastructure: load balancing, TLS termination, caching and compression, and hiding your internal topology.

An API gateway is a reverse proxy built for APIs — layering on auth, rate limiting, request transformation, and routing by path or service.

Quick mental model: forward serves clients, reverse serves servers, and a gateway is a reverse proxy plus API policy.

Nginx is the classic reverse proxy. This config quietly forwards every incoming request to a backend app.

An API gateway routes paths to services — fronting a whole microservice system behind one entry point, as this Nginx routing shows.

Yes — Nginx can be a forward proxy, reverse proxy, or gateway. The role comes from direction and config, not the software itself.

Choosing is about who you protect: outbound client traffic means a forward proxy, inbound to servers a reverse proxy, inbound APIs a gateway.

Test your proxy direction knowledge.

Recap: forward proxies serve clients, reverse proxies serve servers, and a gateway adds API policy. One tool like Nginx can play any role.
