Quite franky, there's a lot in that code that could go wrong.

1.
First of all, all HTTP input/output is based on ASCII encoding. That is
neither a proper encoding for XML nor for HTTP responses. Could work,
could break.

2.
Is application/x-www-form-urlencoded really what you want to use? If you
want to upload a file, that should be "text/xml". Otherwise, your
submitted xml string must be a key/value pair in order to be processed
properly by the receiving web application.
