The items logged and the analysis program are completely configurable using the server manager's HTML forms. Proxy Server supports HTTP, FTP, and Gopher for caching. 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. In addition, Proxy Server helps system administrators implement their own security policies by stopping transmission of MIME types, Java and JavaScript, and ActiveX components. Proxy Server can support a large number of clients. 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.
