Err, the inteface Valve clearly defines:
public void invoke(Request request, Response response, ValveContext context)
throws IOException, ServletException;

I'm not, I'm casting request to HttpRequest so I can call getSession. I did
cut some of my code but I do check to make sure request can be casted.
See org.apache.catalina.authenticator.AuthenticationBase and the method
getSession(HttpRequest request, boolean create);
as this gives a clear example of what I'm trying to do. yet it doesnt work for
me!
