Proxy

Meaning in software engineering, with examples

nounCommon term

In software engineering, proxy means: A server or software layer that receives a request and passes it to another service, often for routing, filtering, or security.

Common in API gateways, corporate networks, testing setups, and browsers. A proxy may hide addresses, add headers, cache responses, or control access.

Example sentences

  2. Our office proxy blocked the webhook callback until we added the staging domain to the allowlist.

    In this case, the proxy acts as a network control point that filters traffic based on policy rules.
