A built-in log analysis program includes reports such as total number of requests, total bytes transfered, most commmon URLs requested, most common IP addresses making requests, performance during peak periods, cache hit rates, and estimated response time reduction. The items logged and the analysis program are completely configurable using the server manager's HTML form. Reverse proxying is used to protect a Web server or database behind a firewall. The proxy server initiates a second connection from it to the Web server, from which it can retrieve data. All of this is transparent to the end user.
Corporate data can remain behind the firewall and yet be accessible to the public as necessary.
To provide additional security, the proxy server can be configured to speak only to the Web server's IP address and vice versa, and the firewall can be configured to allow HTTP traffic only between those two IP addresses. The actual number depends on your hardware configuration and how the network is being used. The real question is how to optimize your network infrastructure. The answer depends somewhat on your network configuration. Please see the iPlanet Proxy Server Deployment Guide for more information.
