Reverse proxy servers provide the following features:

Load Balancing - Reverse Proxy Servers can control incoming requests and reroute them to a designated group of servers. Distributing load on multiple servers increases speed and capacity utilization.

Web Acceleration - Reverse proxy servers can provide features like data compression, caching, SSL encryption, etc., and leaving upstream servers free to do what they are supposed to do.

Security and Anonymity - By sitting in front of the internal network, reverse proxy servers can add another layer of protection against security attacks.
