Session object is created for a specific request and the values in it are accessible within that request whereas Context object is created for web application and the values in it will be accessible for all requests and accessible across the application.
Difference between session and context object ?
Why request object is created per request not reused ?
Request object is created per request not reused because HTTP is a stateless protocol and it does not expect the data to be remembed. But the servlet object is created once not per reuest.
If different request comes from different browsers it creates different request threads rather than different servlet objects.
Can we write static methods in a servlet?
We do not see any static methods in the servlet as the container has to create the servlet class object.
