Java Servlets - 2 minute tutorial

Introduction to HttpServletRequest

Servlets are managed/executed by servlet containers like Apache Tomcat or Jetty.

Whenever a client makes an http request, it is received by the servlet container in http protocol semantics; the servlet then creates an HttpServletRequest object, stuffs it with request parameters, headers, cookies etc that is sent by the client and passes it to the servelt instance for further processing.
