You could implement a javax.servlet.Filter that is mapped to *.do that
pushes and pops to a session based stack.

One trick that can help you, is to create a variable (a bean) in an
action Struts, so that it can be used in the jsp file.
In step 4/5 (in the action struts), you can set :
request.setAttribute("myQuery", request.getQueryString());
And in your jsp file, you can use it, for example, like this :
<bean:write name="myQuery" />
I'm not perfectly sure that it works, but you can try it.
