A Reverse Proxy sits between a client and a web server (or servers) and acts as a frontend by handling all incoming client requests and distributing them to the backend web, database, and/or other server(s).

Other benefits of a Reverse Proxy include:

• Load balancing: The reverse proxy distributes incoming connections to backend servers, and can even do so according to the current load that each server is under.
  • This ensures that none of the backend servers get overloaded with requests.
  • It also prevents downtime, since the reverse proxy can reroute traffic if a backend server happens to go offline.
• Central logging: Rather than having multiple servers generate log files, the reverse proxy can log all relevant information in a single location.
  • This makes the administrator’s job immensely easier, since problems can be isolated much more quickly and there is no need to parse log files from multiple locations when troubleshooting issues.
• Improved security: A reverse proxy will obfuscate information about the backend servers, as well as act as a first line of defense against incoming attacks.
  • Since the reverse proxy is filtering out traffic prior to forwarding it to the backend, only innocuous traffic is passed along to the other servers.
• Better performance: A reverse proxy server can make smart decisions about how to distribute the load across backend servers, which results in speedier response times.
  • Other common server tasks such as caching and compression can also be offloaded to the reverse proxy server, freeing up resources for the backend servers.
