In JSP 1.0 you can transfer the new parameter as a request scope JavaBean.
In the originating JSP you create the JavaBean with <jsp:useBean>, scope
set to "request", and set its properties with <jsp:setProperty>. In the
target JSP you do the reverse; declare a name for the JavaBean with
<jsp:useBean>, again with scope="request", and get the properties with
<jsp:getProperty>, or process them with a scriptlet, or use them as
input values in a new <jsp:setProperty>.
In JSP 1.1 you may be able to just add simple string parameters to the
URL is <jsp:forward> using the regular "?par=value" syntax (it's in the
Servlet 2.2 draft).
