Reverse Proxy Hosting
Reverse proxy hosting is a server setup in which a proxy server sits in front of one or more backend servers, receiving all incoming client requests and forwarding them to the appropriate backend before returning the response.

Reverse proxy hosting is a server setup in which a proxy server sits in front of one or more backend servers, receiving all incoming client requests and forwarding them to the appropriate backend before returning the response.
Overview
A reverse proxy is the opposite of a forward proxy: rather than sitting in front of clients to manage their outgoing requests, it sits in front of servers, intercepting incoming requests on their behalf. Clients only ever interact with the reverse proxy's address, never connecting directly to the backend servers it protects — a setup commonly implemented with software like Nginx or HAProxy, or as a managed Load Balancer service in the cloud. This architecture provides several practical benefits at once: it can distribute traffic across multiple backend servers for scalability, terminate SSL/TLS in one place instead of on every backend, cache and compress responses, and hide the internal network topology from the outside world, which improves security. It's also commonly used to route traffic to different applications or microservices based on the request path or hostname, letting several services share a single public-facing domain. Reverse proxy hosting is a foundational pattern behind Managed WordPress Hosting platforms, content delivery setups, and containerized deployments alike, and it's a core topic in DevOps and networking curricula such as CI/CD with GitHub Actions and Cloud Security, where reverse proxies are frequently used to enforce access control and observability at a single choke point.
Key Concepts
- Intercepts client requests on behalf of one or more backend servers
- Distributes traffic across backends for scalability and reliability
- Centralizes SSL/TLS termination instead of per-backend certificates
- Hides internal server topology, improving security
- Supports response caching and compression
- Routes requests to different services based on path or hostname
