I know that the error comes from the Java program, the nullpointer error.
But what it confused me is: if I'm using an Internet Explorer version 5 to
access the page, it's working fine. If I use HTTP::Request, it'll fail. I tried
to simulate the headers in the IE's request in HTTP::Request, but I failed to
make it work. I just wonder if it's because HTTP::Request doesn't support
HTTP/1.1 and Keep-Alive properly?
