The ServletContext.getRequestDispatcher method takes a String argument describing a path within the scope of the ServletContext. This path must be relative to the root of the ServletContext and begin with a '/'. The method uses the path to look up a servlet, using the servlet path matching rules, wraps it with a RequestDispatcher object, and returns the resulting object. If no servlet can be resolved based on the given path, a RequestDispatcher is provided that returns the content for that path.
1. The requestDispatcher is used for BOTH static and dynamic contents. 2. In the case of static content, no servlet can be resolved on the given path. 3. In that situation, the contents for that path is what you get. 4. Say, taht of an html file.
