For an included JSP page (or servlet), the container adds a number of
request attributes automatically:
javax.servlet.include.request_uri
javax.servlet.include.context_path
javax.servlet.include.servlet_path
javax.servlet.include.path_info
javax.servlet.include.query_string
For a forwarded request, you can add whatever request attribute you like
before you do the forward.
This, and so much more, is described in the Servlet specification. If
you're developing a somewhat complex application with JSP, especially
one including both servlets and JSP, I recommend that you read both the
Servlet specification and the JSP specification, or any good books about
these two technologies. JSP is an extension of the Servlet specification,
so you miss out on a lot of stuff unless you learn about servlets as well:
