CNET: Apache 2.0 Serves Any Protocol
February 25, 2001
"Most experts suggest that a server machine should be dedicated to a single purpose. In other words, a Web server machine should function only as a Web server, while the FTP and mail servers should be on separate machines. This is great in theory, because it minimizes the chance of security holes caused by interaction between two servers. It also keeps one server from affecting the performance of another."
"... With Apache 2.0, the Apache Group has found a way to help. More than a Web server, the latest version of Apache resembles a server framework. It allows you to create modules that honor any protocol, which means you can better manage multiple servers. The original reason the Apache Group designed the architecture this way was so that users could implement new protocols quickly and easily, but it has the added bonus of helping you keep your servers straight."
