Hi,
On this page there are some WFS calls which do work against my TinyOWS server http://188.64.1.61/cgi-bin/tinyows. Feel free to use it for testing.
http://latuviitta.org/Http-POST-ja-Filter.php
A very easy to use tool for testing POST requests is the Poster Firefox extension. This image shows how to use it. It is so simple that it should not matter that the texts I have added are in Finnish http://latuviitta.org/documents/WFS_POST_Poster.png.
