At first, this might not seem worthwhile. After all, there are lots web servers out there. Why switch to Zeus Traffic Manager?

However, for many people, the webserver's role has shrunk. Back in the old days, your webserver probably served up static pages, and generated dynamic content via an API like CGI, FastCGI, ISAPI or mod_php. Nowadays, it's becoming much more common for dynamic content to be generated via its own dedicated app server, like WebSphere, JBoss, BEA WebLogic, Glassfish, and so on. Your webserver still serves the static content, and the dynamic pages are proxied to the app server via HTTP.


This means that your webserver is left with two simple tasks:

1) Delivering static web pages, and
2) Sending HTTP onto the app server.
