Question

If a Web application is deployed on a server ( in my case its apache 7) … And if I try to use different computers to access my web application. It should handle all the requests by itself and create an instance of a web application for each and every different request? Am I right?

Using Dynamic Web Project.

Nope. There is just one instance of the web application deployed from a WAR file. Also there will only be a single instance of each servlet.

The only entities that are created per instance¹ are HttpServletRequest and HttpServletResponse. IF two computers access the exact same URL at the same time, two instances of aforementioned objects will be created and passed to the same servlet.

^{1: Tomcat actually reuses instances of HttpServletRequest and HttpServletResponse after the request is processed. But this is probably a microoptimization, irrelevant to the question.}
