1. If u are having instance variables i.e member variables of servlet class
and not implementing the SingleThreadModel interface then these variables
are shared during various invocations of the same servlet. To avoid
concurrent access of these variables u can either make the code thread safe
by using java synchronized keyword or implement the SingleThreadModel
interface.
2. Since local variables in class methods come into existence only when the
method gets called, they will be created fresh for each method call.
