--> where do cookies get stored ?

--> how does servlet ensure instance persistence ?

--> I noticed that getattribute method is present only in ServletRequest , but not present in HttpServletrequest. Why so, any reason for the same ?

Not a Servlet issue. The browser is free to do as it pleases.

It doesn't.

There's no such method. If you mean getAttribute(), then HttpServletRequest (not HttpServletrequest) inherits it.
