I think I have posted the code.
You posted a class called "RequestHack" which is not a servlet.
I am not aware about the functionality of this cod, somebody else has developed this code.
Have you been in touch with that person yet? That would seem the logical first step.
I havn't used any of the tools.
Then I advise to start with that so you get a better understanding of what's going on at runtime, like which URL redirects to which other one in which sequence.
From the code of "RedirectToSpServlet",I guess, it should be part of redirected URL
That much is obvious. But unless you know which piece of code can redirect to *where* under *which* circumstances, AND you know what is exactly happening at runtime, there's not much chance of this getting resolved, certainly not by anyone in this forum who doesn't have access to any of that information.
