Q.

Identify the techniques that can be used to implement 'sessions' if the client browser does not support cookies.

"Hidden form fields" - marked as correct answer.

Why?
Nothing about it in the Servlet 3.0 specification.
I think it's kind of tricky question..

[admin]

Hidden form fields is a standard HTML concept and is a valid way to maintain a session. The servlet engine has no knowledge of whether a parameter was a hidden form field or a visible form field.
