This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
If there is some arbitrary JSP, say x.jsp, then I rename it to _x.jsp, and then write my own x.jsp which has '<jsp:forward page="_x.jsp"/>', what could possibly appear different to _x.jsp ? i.e. Is there anything that anyone can think of that doesn't cause this request forwarding to appear transparent to the original JSP ?
