Gateway Proxy

Package gateway provides a simple reverse proxy server that can switch between two backends based on the response of the first one.

Overview

The gateway package offers functionality to create a reverse proxy server capable of routing requests to two different backend servers (A and B).
It dynamically switches between the backends based on the response received from the initial request to A.
If A responds with a 404 error and a special header indicating a fallback route, subsequent requests are routed to B.

Note: Routes are cached for performance. To reset the cache, you must restart the server.

Features

• Dynamic Routing: The server dynamically switches between two backend servers based on the response from the initial request.
• Fallback Mechanism: If the primary backend (A) returns a 404 error with a specific header indicating a fallback route, subsequent requests are routed to the secondary backend (B).
• Route Caching: Routes are cached for performance. To reset the cache, you must restart the server.
