POST doesn't work on SOS Server

[xisko]

Hello, MapServer always produces an exception message when I send a DescribeSensor / GetObservation request with POST.

This is an example of request:

<?xml version="1.0" encoding="UTF-8"?>
<DescribeSensor version="1.0.0" service="SOS" 
	xmlns="http://www.opengis.net/sos/1.0" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://www.opengis.net/sos/1.0 
	http://schemas.opengis.net/sos/1.0.0/sosDescribeSensor.xsd" 
	outputFormat="text/xml;subtype=&quot;sensorML/1.0.1&quot;"> 
<procedure>urn:ogc:def:procedure:35</procedure>  
</DescribeSensor>

This is the exception:

<?xml version="1.0" encoding="ISO-8859-1"?>
<ows:ExceptionReport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows" version="1.1.0" language="en-US" xsi:schemaLocation="http://www.opengis.net/ows http://schemas.opengis.net/ows/1.0.0/owsExceptionReport.xsd">
  <ows:Exception exceptionCode="InvalidRequest" locator="request">
    <ows:ExceptionText>msWFSParseRequest(): WFS server error. Unsupported WFS request.</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>

Can anybody help me?

Thanks
