Proxy veikia kaip tarpininkas užklausoms. Tiesioginis proxy yra prieš klientus (juos reprezentuodamas serveriams), o reverse proxy yra prieš serverius (juos reprezentuodamas klientams) — valydamas apkrovos balanso nustatymo, podėlio, saugumo ir daugiau. Reverse proxy yra svarbūs sistemos projektavimo komponentai.
Tiesioginis proxy vs reverse proxy
FORWARD PROXY → sits in front of CLIENTS, forwarding their requests to servers:
Client → FORWARD PROXY → Internet/Server
→ represents the CLIENT (hides client identity); for filtering, caching, anonymity,
access control (e.g. corporate proxies)
REVERSE PROXY → sits in front of SERVERS, receiving requests on their behalf:
Client → REVERSE PROXY → Backend servers
→ represents the SERVERS (clients don't see the backend); the common system-design component
