A reverse proxy is a device or server placed in front of a Web server. Incoming requests are handled by the proxy sever, which retrieves information from the Web server and then forwards it to the user. A reverse proxy can also be deployed to handle SSL acceleration, load balancing, intelligent compression, and caching.
The F5 BIG-IP® product family can work as a reverse proxy, providing SSL acceleration, SSL termination, and re-encryption to Web servers, SSL key management, load balancing, and failover handling.
