The Apache Web server is the best, and most popular, HTTP server software in use on the Internet today. In your production enviroment using Geronimo with the Apache Web server would give you some rigorous advantages as given below.

1. Clustering & Load Balancing
   Clustering allows an application server to support multiple nodes with failover, session data sharing, and load balancing across many network nodes. Load balancing of the application can be done with the help of inbuilt support of Apache server.

2. SSL Encoder
   The advantages of Web server proxies are that they offer a way to get server affinity for SSL-encrypted messages, without any extra hardware. But extensive SSL processing puts an extra load on the proxy. It will be handled by Apache server while Geronimo can handle business logic of the application.

3. Application Load Sharing
   In many serving systems, web and application servers work together to handle all HTTP requests. Apache handles the request for static pages (including HTML, JPEG, and GIF files), while Geronimo handles requests for dynamic pages (JSPs or servlets) with the help of Tomcat/Jetty. Geronimo servers can also handle static pages, but in combined systems, they are usually configured to handle dynamic requests.
