1. ServletContext is a window by which a Servlet instance see its environment.
2. ServletContext defines some methods that a Servlet instance can use to communicate with Servlet Container. E.g. To dispatch request, Writing to a log file etc.
3. Servlet Container pass the ServletConfig object to the Servlet instance when calling init(ServletConfig config) method. ServletContext instance reference exist inside the ServletConfig object.
4. Each Web application has only one ServletContext instance. So its a singleton object. If an Servlet Container deploys multiple Apps, each App have its own ServletContext.
