Hi,
I have some difficulties to understand the terms of the components in the Apache. Does anyone have good reference site or explain to me ? Like What is servlets ?

I did find out that the servlets is a Java server side application that runs inside a network device, such as a web server. It responds to requests from clients, accepting client input and dynamically generating output.

From this statement, I found another question is what is means by Java server side application? Is this mean it runs only in the Server has Java program ?

What is the Servlet Zone ?

Although we can get the explanation from the documents, sometimes I will have more questions on the explaination I get.

Please help me on this!!! Thanks
