The year is 2007. Java and SOAP applications have taken over the
internet. The default response to any HTTP request is "500 Internal
server error." You, the fearless programmer, must devise a way to trick
each server into not crashing on your requests, without the benefit of
error messages, logs, or standard-compliance. XML whitespace tweaking?
Tag reordering? MIME header reformatting? ROT13 encoding? Nobody hears
Your only chance is a powerful new weapon: http-twiddle.el.
