I think redirect to same domain:ip in same browser tab page should keep
session.
MG2>2 alternatives: build out HTTPGet with ¶ms
* Calls the {@link HttpServletResponse#sendRedirect(String) sendRedirect}
* method to the location specified. The response is told to redirect the
* browser to the specified location (a new request from the client). The
* consequence of doing this means that the action (action instance, action
* errors, field errors, etc) that was just executed is lost and no longer
* available. This is because actions are built on a single-thread model. The
* only way to pass data is through the session
MG2>with chain interceptor
* or with web parameters
* (url?name=value) which can be OGNL expressions.
MG2>essentially a HTTP Get with params............. here is example:
* <!-- START SNIPPET: example -->
* <!--
* The redirect URL generated will be:
* /foo.jsp#FRAGMENT
* -->
* <result name="success" type="redirect">
* <param name="location">foo.jsp</param>
* <param name="parse">false</param>
* <param name="anchor">FRAGMENT</param>
* </result>
* <!-- END SNIPPET: example -->

MG2>Here is code that *should access session params* to pass to new
finalLocation (but session is not accessed?)
/**
* Redirects to the location specified by calling
* {@link HttpServletResponse#sendRedirect(String)}.
*
* @param finalLocation the location to redirect to.
* @param invocation an encapsulation of the action execution state.
* @throws Exception if an error occurs when redirecting.
