CORE DEFINITION

Provide a surrogate or placeholder for another object to control access to it.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Control access and enhance functionality. A secretary is a proxy for the CEO; a CDN is a proxy for the server. As a scaffold, it teaches us to establish a 'buffer' between core resources and external requests: performing permission control, cache acceleration, or logging to protect the core from direct impact.

anchor

Anchor fast decisions

Insert a proxy object between the client and the target object, with the proxy intercepting and controlling access to the real object. The proxy can add enhanced logic such as permission checks, caching, logging, or lazy loading before and after forwarding requests; the real object remains transparent to the client, which believes it is interacting with the real object, but all calls are actually routed through the proxy.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Define an interface implemented by both the real object and the proxy
The real object implements core business logic
The proxy holds a reference to the real object and adds control or enhancement before forwarding
The client calls the proxy through the interface rather than the real object.
