How Container Handles Servlet Request

Question : How web container handles the servlet request?

Ans : The web container is responsible to handle the request. Let's see how it handles the request.

• maps the request with the servlet in the web.xml file.
• creates request and response objects for this request
• calls the service method on the thread
• The public service method internally calls the protected service method
• The protected service method calls the doGet method depending on the type of request.
• The doGet method generates the response and it is passed to the client.
• After sending the response, the web container deletes the request and response objects. The thread is contained in the thread pool or deleted depends on the server implementation.
