Inter Servlet Communication

For Inter Servlet Communication, we use two types of Interface:

• RequestDispatcher

RequestDispatcher generates both Request and Response. It has two methods:

• forward() is to forward the servlet or to go to the next servlet.
• include() is to include the previous servlet to the new one.

• SendRedirect

It is used when we don't require the response for security purposes.
