I have the following concerns whenever the redirect is used:
* The statement response.sendRedirect("/somePage.jsp")
will bind the codes statically to the underlying file system
structures. So if someone moves the somePage.jsp to
a different location, the codes are broken.
* The JSP page somePage.jsp could not be protected
by the standard security constraints. So it is recommended
to use response.sendRedirect("/someAction.do") or
a Filter, either way that provides security checking.
Improper use of the redirect could make the security
constraints over complicated as in an early discussion on
how we redirect to restricted pages.
* Use the redirect only when it is really needed. It needs
extra CPU time and network resources than just forward.
Regarding to the last concern, I have a question: what
business requirements that need the redirect within
a web application? Using the redirect across web
applications or web sites is reasonable as well as when
we dynamically build hyper links.
A delay at client side? Any more ideas?
